Pesticide exposure during greenhouse applications. Part I: Dermal exposure reduction due to directional ventilation and worker training; Part II: Chemical permeation through protective clothing in contact with treated foliage
Workers conducted benchtop handgunning spray operations in commercial greenhouses with the ventilation system either on or off. Both video-imaging analysis and patch sampling indicated that when spray painting occurred with ventilation on rather than off, dermal exposure was reduced for experienced applicators, but increased for inexperienced applicators. No difference was observed between the two groups with ventilation off. Protective clothing performance was evaluated with particular reference to the hazard of contact with wet or treated foliage. Breakthrough times for four commercially available garments are reported. It was concluded that none of the garments can be considered chemical resistant under the use conditions observed. Contact with treated foliage represents a special hazard during greenhouse applications, and many chemical protective clothing products in current use are inadequate for worker protection. These products should be redesigned and field-tested.

A history of process and chemical changes for fungicide application in the western Canadian lumber industry: What can we learn?
The article examines historical changes in anti-sapstain fungicide application in the western Canadian lumber industry. Modifications have included (1) changes in fungicide formulations, (2) substitution with new fungicides, and (3) changes in application technology. The data were collected during three related epidemiologic studies. It was discovered that chlorophenate formulations and application technology were changed without systematic collection of data to evaluate their impact on worker exposure. It was also found that substitution of new fungicide active ingredients occurred before a full package of toxicological data was available about the substitutes. Active targeting of chemicals requiring substitution, establishing systematic rules for the introduction of new chemicals into the workplace, and inclusion of all affected stakeholders in the decision-making process may help to ensure that future substitutions are made on the most rational basis possible.

Biomarkers of human exposure to pesticides
Occupational or environmental exposure to pesticides can be revealed either by the presence of a substance or its metabolites in urine, blood or some other easily sampled medium, or by the observation of a biochemical effect such as enzyme inhibition, reaction with proteins such as receptors or antibodies or mutation. A general review is followed by 17 separately authored papers under the headings "molecular characterization", "biomarker measurement methods" and "data analysis and application to risk assessment". Compounds and compound classes covered include nitriles, dioxins, organophosphorus insecticides, 2,5-hexanedione, p-nitrophenol, and chlorophenoxyacetic acid herbicides.

Estimation of long-term exposure to pesticides
An exposure index was developed to estimate long-term dermal and inhalation exposure of bulb farmers to pesticides. The proposed index consists of generic levels of exposure specific to the method of application and is further determined by farm-related parameters such as acreage and number of pesticide applications. Ranking of 127 bulb farmers according to calculated lifetime dermal exposure correlated only moderately to ranking based on duration of exposure. The proposed index could provide a useful estimate of long-term exposure to a mixture of pesticides in epidemiological investigations.

A sampling and analytical method for the simultaneous determination of multiple organophosphorus pesticides in air
A sampling and analytical method for organophosphorus pesticides was developed using a combined filter/XAD-2 sorbent sampler and gas chromatography with flame photometric detection. The method was evaluated for 19 organophosphorus pesticides based on joint OSHA/NIOSH criteria. Samples were stable for 30 days of storage under either ambient or refrigerated conditions. The 19 compounds studied can be determined over a range of 0.1 to 2 times their exposure limits with an accuracy of ±25% of the true value 95 times out of 100.

Personal exposure to pesticide among workers engaged in pesticide container recycling operations
Environmental exposure monitoring and biological monitoring were carried out among workers engaged in pesticide container recycling at three regional collection sites, a central collection and washing facility and at a steel mill. Exposure levels were highly variable, partly owing to work practices and lapses in protection. Highest levels of exposure were observed for metal washing, metal crushing and metal shredding; sorting and plastic shredding were intermediate and metal melting was associated with very little exposure. Recommendations are proposed for the protection of workers.

Potential parental exposure to pesticides and limb reduction defects
The effects of the potential pesticide exposure of parents on the risk of limb reduction defects in their offspring was studied in a case-control study utilizing New York State Congenital Malformation Register data. Persons with limb reduction defects and controls were compared in terms of parental occupations and counties of residence. Parental occupations and industries reported on birth certificates were qualitatively rated by industrial hygienists to estimate potential pesticide exposures. Residential exposures were estimated from agricultural census data according to county of residence. Neither parental exposure to pesticides nor farming occupation had an effect on the risk of total limb reduction defects. Those persons with limb reduction defects who had additional defects showed weak but consistent elevated risks in relation to parental occupational pesticide exposure. Cases of limb reduction defect with additional malformations appear to be associated with parental occupational pesticide exposure. In appendix: detailed data on potential pesticide exposure based on hygienists' assessments.

Pest control in agriculture - Occupational safety and health aspects
Betichut vegihut taasukatit behadbarat mezikim bechaklaut [in Hebrew]
The use of synthetic pesticides in agriculture, and in particular in glasshouses and in aerial spraying, constitutes a major occupational hazard. Solutions such as the wearing of full respiratory, head and body protective equipment could be very effective, but are rather impractical because of the relatively high cost and the reluctance of workers to use such equipment, particularly in warm, humid climates. A new approach based on the use of alternative, less-hazardous pesticides was studied. The neem tree provides a number of active natural pesticides. One of these is azadirachtin, a terpenoid which disrupts the metamorphosis of insect larvae, inhibits molting, and thus eliminates insects by stopping their growth. It also acts as a repellent which protects plants by keeping insects away. Toxicity tests show a negligible effect on humans, warm-blooded animals, bees and most other species useful to people; the substance is non-mutagenic, with no adverse immune response, and is non-irritant to skin or eyes. Tests in Israeli glasshouses have shown its efficiency in the protection of plants of many types.

Strategies for determining occupational exposures in risk assessments: A review and a proposal for assessing fungicide exposures in the lumber industry
The main strategies for determining exposures for risk assessment were reviewed to select an exposure monitoring protocol for assessing the occupational risks of fungicides in the lumber industry. The methods of application and opportunities for exposure were analyzed in a survey of lumber industry worksites using fungicides. This review illustrates some of the problems with each method and indicates some of the issues that should be investigated in order to determine the optimal strategy for a specific exposure scenario. It suggests that potential for bias must be assessed for each of the strategies that do not entail population-based sampling.

Determination of handwash removal efficiency: Incomplete removal of the pesticide chlorpyrifos from skin by standard handwash techniques
To develop standard procedures for evaluating the removal efficiency of handwash techniques, a known amount of the insecticide chlorpyrifos was transferred to volunteers' hands, which were then washed by standard techniques. Time between exposure and washing, the amount of washing solvent and skin loading were measured. Prewashing with ethanol increased removal efficiency; removal efficiency immediately following contact decreased for lower skin loading levels. Substantial amounts of the insecticide were either absorbed or adsorbed through the skin, and pesticide residue levels recovered by standard handwashing techniques did not represent accurate estimates of dermal exposure. Appropriate laboratory-based removal efficiency studies should be conducted prior to field investigations if handwashing is to be used to estimate dermal exposure in the workplace.

Delayed-type allergenicity of triforine (Saprol)
In a study of chrysanthemum growers exposed to triforine (1,4-bis (2,2,2-trichloro-1-formamidoethyl) piperazine), the highest rate of positive patch test reaction was seen to triforine among the seven pesticides and chrysanthemum extracts tested. A higher prevalence of work-related skin symptoms was seen in subjects with a positive patch test reaction to triforine than in those with negative reactions to all allergens tested. The study indicates that delayed-type allergy may be induced among chrysanthemum growers by triforine and other pesticides, as well as by chrysanthemum itself.

Assessment of omethoate and fenitrothion absorption in greenhouse workers using personal protective equipment in confined areas
Valutazione dell'assorbimento di ometoato e fenitrothion durante lavorazioni eseguite con l'uso di mezzi personali di protezione in ambienti confinati [in Italian]
Sprayers and workers engaged in manual operations in a greenhouse were monitored for exposure to omethoate and fenitrothion. Urinary dialkylphosphates (dimethylthiophosphate and dimethylphosphate) were used as the biological indicators of exposure to the two chemicals. Residues of fenitrothion on foliage were measured as well as levels of fenitrothion and omethoate in air samples collected in the breathing zone (personal sampling) and in the workplace near the entrance and the end of the greenhouse (static sampling). Skin exposure was estimated from pads placed on the thorax under overalls and from hand washing liquid at the end of the workshift. Sprayers wore respiratory and skin protection during the workshift. Workers engaged in manual operations did not wear respiratory protection. Re-entry to the greenhouse was permitted 48h after spraying. Levels of omethoate and fenitrothion in air samples, on pads and on the hands, during manual operation on ornamental plants, were very low. Urine analysis showed no significant difference between levels of urinary dialkylphosphates in the control group and exposed workers. Cholinesterase activity (acetyl and butyryl) showed no significant reduction at the end of the workshift compared with baseline values.

Allergic disease due to pesticides - Three case reports
Allergopatie da pesticidi - Descrizione di tre casi [in Italian]
Most studies of pesticides have focussed on their acute or chronic toxicity. However, at present exposure levels severe intoxication is rare and it is appropriate to look more closely at their sensitizing power. Three cases are reported - one case of urticaria/angio-oedema, one of asthma and one of oculorhinitis. Only one subject was atopic. The substances to which sensitization was found were Cynoxamil, Mancozeb, Tiofanate, Seccatutto for the first case, Paraquat for the second and Dodine for the third. The need to extend allergological tests to pesticides also when workers show clinical signs with suspected immunological pathogenesis is highlighted. Furthermore, in order to reduce the number of new cases of pesticide allergy, closer monitoring of subjects exposed to low doses is also proposed.

Health costs and benefits of fungicide use in agriculture - A literature review
Acute and chronic health effects associated with six major chemical categories of fungicides are described. Effects include allergic dermatitis and skin or mucous membrane irritation. Some fungicides also show carcinogenic and mutagenic effects in animals. Since unopposed fungal growth may lead to the formation of mycotoxins in food and other substances, judicious use of fungicides is required in order to obtain a balance between adverse effects from fungicides and mycotoxins.

Non-Hodgkin's lymphoma and agricultural practices in the prairie provinces of Canada
The aim of this study was to provide an update of a cohort study (1971-1985) that previously reported a significant risk of non-Hodgkin's lymphoma among male Saskatchewan farm operators (see CIS 92-1589) according to fuel-oil expenditures and herbicide spraying for farms less than 100 acres (2570 hectares) by including two additional Canadian prairie provinces, two additional years of follow-up, and data from the 1981 Census of Agriculture. The addition of a further two years of follow-up resulted in lower risk estimates associated with herbicide spraying for Saskatchewan. A significantly increased risk of non-Hodgkin's lymphoma according to acres sprayed with herbicides was observed for the three provinces combined when the herbicide spraying data from the 1991 Census of Agriculture was used. Although the current results are not entirely consistent with the original Saskatchewan analysis, they support the overall finding of an association between herbicides and risk of fatal non-Hodking's lymphoma.

Cholinesterase activity of Senegalese applicators exposed to organophosphates (fenitrothion)
Exposition au fénitrothion et activité cholinestérasique chez des applicateurs de pesticides au Sénégal [in French]
Among the pesticides currently used in agriculture, organophosphates occupy a dominant position. They have a specific action in inhibiting enzymes, namely cholinesterases. Given the number of cases of human poisoning in agriculture, it is important to measure levels of cholinesterases to evaluate the risks. Cholinesterase activity was measured with Ellman's colorimetric method in whole blood, erythrocytes and plasma of workers exposed to Sumithion (fenitrothion 500g/L U.L.V. and C.E.) in Senegal, which is one of the most commonly used organophosphate insecticides in that country, and as a function of the spraying equipment used and of the type of application. Prevention of cases of poisoning calls for medical, technical and hygienic measures, and, above all, for the health education of workers. A systematic determination of globular and plasma cholinesterases is recommended at the time of the initial medical examination of workers, the results of which can then be used for comparison purposes during later tests.

Dioxins in blood from Swedish phenoxy herbicide workers
This brief communication presents the results of a follow-up study of 5 workers employed between 1964 and 1978 in a Swedish factory which produced chlorophenoxy herbicides and 2,4,6-trichlorophenol. Blood plasma analysis indicated that the workers had much higher levels of 2,3,7,8-tetrachloro-p-dibenzodioxin (TCDD) than did five referents. A relationship was observed between employment time and values of TCDD. Values of other dibenzodioxins and dibenzofurans and of non-ortho-polychlorinated biphenyls (PCBs) were also higher in the workers.

Health status of pesticide applicators with attention to the peripheral nervous system
A health status survey was carried out on 102 pesticide applicators employed for over nine years and potentially exposed to a variety of fertilizers, herbicides and fungicides. As a group, the applicators were healthy save for abnormalities in nerve conduction studies in 29 subjects. Further studies revealed no evidence of exposure-related peripheral neuropathic symptoms or nerve conduction study effects and no significant differences in these endpoints between the pesticide applicators and a control group. Limitations of the study are discussed.

Methyl bromide - Use and hazards for applicators and consumers
Bromure de méthyle, son emploi, son danger pour l'applicateur et le consommateur [in French]
Methyl bromide is a widely used fumigant and soil disinfectant which is cheap, efficient and quite easy to apply. In exposed people, lung, skin, gastro-intestinal tract and, in particular, central nervous system toxicities have been reported. Methyl bromide is potentially highly dangerous because: it is colourless and almost odourless, so that severe exposure could occur unknowingly; toxic manifestations are delayed and could develop hours after the exposure; there is no known antidote; repeated exposures to low concentrations may be harmful (neurological and psychiatric sequelae have been described). Safety regulations about its use should be strictly followed and enforced. Applicators should be properly trained.

High sperm density among members of organic farmers' association
In a Danish study of reproductive effects of pesticides in male greenhouse workers, an unexpectedly high sperm density was found in members of an association of organic farmers who manufacture their products without the use of pesticides or chemical fertilizers. This is in contrast to a world-wide decreasing trend of sperm density in the general population. No hypotheses are put forward to explain this finding.

Nordic Expert Group for Documentation of Occupational Exposure Limits. 108. Ethylenebisdithiocarbamates and ethylenethiourea
Nordiska Expertgruppen för Gränsvärdesdokumentation. 108. Etylenbisditiokarbamater och etylentiourinämne [in Swedish]
A critical survey of the literature relevant to the discussion of an occupational exposure limit for ethylenebisdithiocarbamate (EBDC) fungicides (maneb, mancozeb and zineb) and ethylenethiourea (ETU) is given. The critical effects of exposure to EBDCs are toxic effects on the thyroid gland, and their sensitizing, cross sensitizing and cross-reactivity properties. Mancozeb is also a possible carcinogen. The critical effects of ETU are directed towards the thyroid gland, where ETU induces thyroid hyperplasia and follicular carcinomas at low doses. The occupational exposure limits for EBDCs are based on their sensitizing properties, on their effects on the thyroid gland and their possible carcinogenic effects in rodents. The main emphasis in the occupational exposure limit for ETU is on its goitrogenic and thyroid carcinogenic properties. There is a need to emphasize the significance of biological monitoring, and to reduce exposure to EBDCs and ETU rather than develop more detailed occupational exposure limits. It is important, therefore, to delineate dermal absorption, and the metabolic pathways of EBDC fungicides and ETU for the development of biological monitoring methods. Moreover, an understanding of the effects of these fungicides on the thyroid is crucial for adequate risk assessment.

Biological monitoring of occupational pesticides exposure
Two methods are used in monitoring occupational exposure to pesticides: measurement of the unchanged pesticide or its metabolites in biological samples such as blood or urine and measurement of a biochemical effect such as the inhibition of blood cholinesterase activity. The method measuring a biochemical effect has mostly been used for exposure evaluation and determination of dose-response relationships of acute levels of organophosphates and carbamates in humans. The method of measuring the unchanged pesticide or its metabolites has been used to confirm exposure or estimate the internal dose. It provides no information on the potential health risks.

Pesticide poisonings in Costa Rica
A descriptive epidemiologic study conducted in Costa Rica investigated the incidence of pesticide poisoning with special attention to agricultural workers and occupational exposure. Information from 3 national registers (occupational accident and disease reports, hospitalizations and deaths) were used. During 1986, 1800 occupational accidents caused by pesticides were reported; between 1980 and 1986, 3330 persons were hospitalized and 429 died. Cholinesterase inhibitors caused 71% of the reported occupational accidents, 63% of the hospitalizations and 36% of the deaths. Paraquat caused 21% of the occupational accidents, 24% of the hospitalizations and 60% of the deaths. Hospitalizations and deaths were 13 and 11 times more frequent, respectively, among agricultural workers than among the rest of the population. High-risk groups for occupational poisonings included agricultural workers aged 15-29 years, female workers and banana plantation workers. The yearly incidence of symptomatic occupational pesticide poisonings among agricultural workers was estimated at 4.5%.

Contact dermatitis from dazomet: Seven cases
Dermite de contact au dazomet: 7 cas [in French]
Dazomet is used as a soil disinfectant which acts by hydrolytic release of methylisothiocyanate. In spite of its resulting high toxicity, cases of contact dermatitis and/or systemic poisoning have rarely been published. Seven cases of contact dermatitis from dazomet are reported here. Lesions were observed on hands and forearms (5 cases), feet and legs (6 cases), face (1 case), trunk (1 case) and buttocks (1 case); in all cases but one they were bullous. No case of systemic poisoning was identified in this series, but biological tests were performed in only two patients. Contact dermatitis from dazomet generally results from mishandling and can be easily prevented.

Studies of pesticide contamination in root-crop farming
Untersuchungen zur Pestizidkontamination bei Hackfruchtpflegearbeiten in Landwirtschaftsbetrieben [in German]
Dermal exposure pads were attached to the skin of the chest, arms and legs of 61 farm workers spraying root crops with pesticides. The pesticide concentrations found on the pads of workers wearing protective clothing were low. However, concentrations as much as 77.2% in excess of the tolerable dermal dose were found when no protective clothing was worn. Of the 61 workers, 24 had health problems such as headache (23), vision disturbances (11) and dermatitis (2).
