Risk of cancer in pesticide applicators in Swedish agriculture
The risk of cancer was analysed in a cohort of 20,245 licensed pesticide applicators (99% male) in agriculture who had licences issued between 1965 and 1976. The mean follow up time was 12.2 years. 558 malignant tumours were found (649.8 expected), which resulted in a statistically significantly decreased standardised incidence ratio (SIR) of 0.86 (95% confidence interval (CI):0.79-0.93). Significantly decreased risks of cancer were also found for liver (SIR = 0.45, 95% CI:0.18-0.93), pancreas (SIR = 0.50, 95% CI: 0.26-0.87), lung (SIR = 0.50, 95% CI: 0.35-0.68) and kidney (SIR = 0.53, 95% CI: 0.32-0.84). SIR for testicular cancer was increased (18 cases, SIR = 1.55, 95% CI: 0.92-2.45) and increased with period since licence. For those born in 1935 or later a non-significant increased overall risk of cancer was observed. Comparisons were made with agricultural workers in general since pesticide applicators are mainly farmers that use or have used pesticides to a greater extent. Higher risks for pesticide applicators were found for testicular cancer, tumours of the nervous system and endocrine glands, and Hodgkin's disease.

Occupational illness from cholinesterase-inhibiting pesticides among agricultural applicators in California, 1982-1985
California pesticide illness investigation reports involving toxicity category I or II organophosphate and carbamate pesticide exposures among agricultural pesticide applicators were reviewed for the years 1982-1985. The pesticides associated with each illness were recorded, and the exposures were classified as chronic, short-term, or accidental. Illnesses were associated with a range of pesticides, including both organophosphates and carbamates in both toxicity categories I and II. Approximately 19% of the illnesses were due to accidents. Overall, the analysis identified a need for improving occupational health surveillance and the regulations governing worker health and safety.

2,4-Dichlorophenoxyacetic acid (2,4-D) - environmental aspects
Conclusions of this study on the ecological effects of 2,4-D: No direct toxic effects, acute or long-term, of 2,4-D applications under field conditions on any animals species have been observed thus far. There are inevitably, indirect effects resulting from the intended selective herbicidal properties of the compound. These effects would result from the use of any herbicide or from other methods of land management. There will, therefore, be effects for mammals, birds, and insects because of food deprivation, modification of habitat, requirements for nesting, shelter, etc. The application of 2,4-D appears to be less hazardous to the beneficial epigeal arthropod community than physical cultivation.

No cases of accidental poisoning have been reported as a result of occupational exposure. Skin sensations, reported by a number of authors to have occurred during field studies, generally lasted only a few hours and did not persist for more than one day after exposure. Neurological signs were not observed. General medical and extensive clinical blood-chemistry studies, and electrophysiological studies on selected motor and sensory nerves in the legs and arms did not show any abnormalities.

Cancer risk in a cohort of licensed pesticide users
First admissions to the hospital among 25,945 men living in southern Piedmont (Italy) and holding a license authorising them to use pesticides were analysed in a study of the cancer risk related to exposure to pesticides. Standardised incidence ratios significantly higher than 1 were encountered for malignant skin cancers and lymphomas. The risk of lymphoma was particularly high in predominatly arable areas. The standardised incidence ratios for tumours of the nervous system and haematopoietic tissue showed an interesting age-related pattern and a higher risk in areas primarily devoted to forest tree plantation, but did not reach significance.

Triazine herbicides and ovarian epithelial neoplasms
The possible role of a class of herbicides, triazines, in ovarian carcinogenesis has been evaluated in a population-based case-referent study. Women previously exposed to triazines showed a significant relative risk of 2.7 for ovarian neoplasms. Although none of the doses could be quantified for the study subjects, 2 risk trends in favour of the plausibility of the association were found: the first by duration and the second by probability of exposure. The population representativity of the study and the comparability of information between the cases and referents suggest the lack of any major bias in the results. Triazine-related risk remained consistent when the analysis was restricted to farmers and when the exposure to other herbicides and to other types of cultivation were considered. Unexposed farmers had the same risk as unexposed non farmers.

Morbidity among employees engaged in the manufacture or formulation of chlorpyrifos
The prevalence of selected illnesses and symptoms during 1977-85 was compared between 175 employees potentially exposed to the organophosphate insecticide chlorpyrifos and 335 matched controls with no history of exposure to organophosphates. Subjects were subdivided into three exposure intensity groups on the basis of job title and air monitoring data for dose response testing. This classification scheme was shown roughly to correlate with plasma cholinesterase inhibition in the workers. No statistically significant differences in illness or prevalence of symptoms were observed between the exposed and unexposed groups or among the three exposure subgroups. Potentially exposed employees did report symptoms of dizziness and of malaise and fatigue relatively more often than subjects from the comparison group; however, further analyses by exposure level, process area, or time did not support a relation with exposure. No cases of peripheral neuropathy were seen among the exposed workers. Although the sample size was small and the statistical power limited, the cumulative exposures likely to have been experienced by this workforce exceed those to be expected for individuals using the product as recommended. The absence of exposure related adverse effects, including neurological impairment, is reassuring.

Pesticides in intensive cultivation - Effects on working conditions and workers' health
Efectos de los plaguicidas en trabajadores de cultivos intensivos [in Spanish]
A study to investigate the effects of pesticides on the health of workers engaged in intensive cultivation was carried out in Argentina during 1983 and 1984. Surveys and interviews were conducted in two groups of workers, flower and ornamental plant growers. 12.3% of the flower growers and 18.6% of the plant growers had symptoms of acute poisoning, with no difference regarding the different tasks. However, the number of flower growers with symptoms of chronic poisoning was significantly greater for the pesticide applicators than for other workers in the same group. Among both groups, 65% of the manifestations were in the central nervous system or peripheral nerves. It was noted that protective measures taken by the workers were insufficient. Guidance on ways to improve working conditions, in particular the use of protective equipment, and promotion of appropriate technology are recommended. Summary in English. Also published in English in the Bulletin of the Pan American Health Organization (Vol.21, No.4, 1987).

Pesticide illness surveillance: The Nicaraguan experience
Vigilancia de las enfermedades provocadas por plaguicidas: la experiencia nicaragüense [in Spanish]
A pilot project aimed at improving the surveillance of diseases caused by pesticides was initiated in 1984 in two provinces of Nicaragua (León and Chinandega). In order to detect the degree of exposure to organophosphorus compounds, cholinesterase screening was performed. The percentage with low cholinesterase activity level (50% or less) increased sharply during the peak spraying season. Airfield workers were most affected. Workers who used certain types of personal protective equipment were significantly less affected. A relatively high rate of 74.6 poisoning cases per 100,000 inhabitants was reported. 94% of the cases reported via questionnaires were occupationally related, small farms being the most affected. Methyl parathion was implicated in roughly half of these cases, two-thirds of which were due to cutaneous exposure. Recommendations include: reduction of methyl parathion use, installation of closed systems for safer aircraft loading, provision and use of skin-protective clothing, and restriction of pesticide work by minors. Summary in English. Also published in English in the Bulletin of the Pan American Health Organization (Vol.22, No.2, 1988).

Biological indicators for the assessment of human exposure to industrial chemicals: Aromatic amines, aromatic nitro compounds, carbamate pesticides, nickel
The available data on the human health effects, metabolism and biological indicators of these substances are reviewed. Conclusions reached: for aromatic amines and aromatic nitro compounds, determination of methaemoglobin level is used for detecting recent exposure to those compounds capable of oxidising haemoglobin iron, along with measurement of the compounds or their metabolites in urine; the internal dose and level of exposure to carbamates can be assessed by determination of their urinary metabolites; for carbamate insecticides with anticholinesterase activity, blood cholinesterases can be used as bioindicators of absorption and effect; determination in plasma/serum and urine are the most useful methods for biological monitoring of nickel exposure.

Toxicologie characteristics and nature of combined effect of a mixture of orthomenthane hydrocarbons
Toksikologičeskie svojstva i harakter kombinirovannogo dejstvija smesi ortomentanovyh uglevodorodov [in Russian]
B-100, a plant growth regulator preparation, is a mixture of o-methane, o-mentha-1,4-diene and o-cymene (o-methylcumene). Its intragastric LD50 for mice was 4950 (3960-6190)mg/kg and 5100 (4200-6300)mg/kg for rats. It had slight cumulative, mild local irritating, skin-resorptive effects and effects on mucous membranes. Combined effects were analysed by linear regression using a computer. The combined effect was less than additive under the conditions of intragastric administration and additive in the case of inhalation. Thus, for establishing an exposure limit for B-100, all 3 components can be considered equivalent.

Evaluation and prevention of occupational hazards due to the spraying of pesticides on railway property
Evaluation et prévention des risques professionnels de l'épandage d'herbicides en milieu ferroviaire [in French]
The use of new herbicides and weed-control techniques by railways has entailed an improvement of working conditions and a reduction in the risk of contamination. An analysis of working conditions aboard a regional weed control train is followed by an evaluation of the medical surveillance of exposed workers by means of a questionnaire addressed to their physicians. The animal and human toxicity of the agents used (aminotriazole, atrazine, synthetic growth regulators) is reviewed, as is the regulation of herbicide use. A protocol for clinical and biological monitoring of exposed workers is proposed, as part of intensified safety and health measures to prevent possible long-term effects.

Toxicology and hazard evaluation of cyanide fumigation powders
The typical fumigant powder is a mixture of 40% sodium cyanide (NaCN) and 60% kaolin. The acute oral toxicity of the mixture is proportional to its NaCN content; kaolin does not modify the toxicity of the NaCN. Release of hydrogen cyanide (HCN) gas from wetted powder gave potentially lethal concentrations of HCN at an application rate of 5g/m3, which is 5 times the recommended rate. The concentration produced by 1g/m3 was significant but not lethal. Application of fumigant powder to the eyes of rabbits produced conjunctivities and keratitis, and was ultimately lethal. Lethal amounts of cyanide were absorbed by abraded skin and moist intact skin, but not by dry intact skin. Thus, protective clothing and equipment should always be worn when cyanide fumigant powders are handled.

Hygienic significance of air pollution with tobacco dust
Gigieničeskoe značenie zagrjaznenija vozdušnoj sredy tabačnoj pyl'ju [in Russian]
This literature survey presents in concise form data on tobacco production at home and abroad, chemical composition of tobacco and health effects of tobacco dust on experimental animals and tobacco industry workers. Nicotine, pesticide residues and flavourants seem to be the main health hazards in the industry. Experimental data on animals are consistent with field observations on humans. Female tobacco workers often suffer late toxaemia of pregnancy, abnormal pregnancy interruptions and weakness in labour. Infants born to exposed mothers more frequently show signs of asphyxia and congenital anomalies at birth than those of control women. Tobacco workers suffer allergic disorders in the form of allergic rhinitis, sinusitis, tonsillitis, bronchitis, hepatitis and asthma. Occupational exposure to tobacco dust also affects the cardiovascular system (strong palpitation, heartache, dyspnoea). Arterial hypertension, hypotension, S-A bradycardia, tachycardia and arrhythmia have also been observed. The data call for further probing of the biological effects of tobacco dust, hygienic evaluations of tobacco manufacturing undertakings' environmental conditions and working out of measures for controlling atmospheric pollution by these undertakings.

Twenty years experience in dermatological testing of herbicides and pesticides
Zwanzigjährige Erfahrungen bei der hauttoxikologischen Prüfung von Pflanzenschutz- und Schädlingsbekämpfungsmitteln [in German]
Dermatological testing forms part of the certification procedure of herbicides and pesticides. It is carried out according to national standards (TGL) and take into consideration relevant regulations issued by the US Environmental Protection Agency, the Organization for Economic Cooperation and Development and the UN Food and Agriculture Organization. A national coordination group sets up priorities for the substances to be tested. Sensitisation tests are particularly required by the chemical industry; they are going to be increased in quantity. There is participation in various national and international research activities. A new test programme using epidermal cell cultures is being developed.

Storage of approved pesticides: Guidance for farmers and other professional users
This guidance note is intended to help farmers and other professional users (non-agricultural usage of timber and masonry treatment products and of public health insecticides) who are responsible for storing approved pesticides. It should not be used as guidance for the storage of fumigant gases in cylinders (eg. methylbromide, hydrogen cyanide etc.), which should be securely stored in the open air and for the storage of pesticides in circumstances where the quantity stored creates a fire hazard. Content: statutory requirements; criteria for pesticide storage; application of criteria to chests, bins, vaults and cabinets; application of criteria to buildings; other considerations (electrical installation, water sypply, records, first aid); associated facilities (including training of personnel using the pesticide store).

Impact of different routes of chlorinated phenoxy acid administration on the microsomal oxidation processes in the liver
Vlijanie različnyh putej vvedenija hlorproizvodnyh fenoksikislot na processy mikrosomal'nogo okislenija v pečeni [in Russian]
Study of the liver detoxification system and the corresponding metabolic processes with respect to different routes of administration (intragastric and percutanous) of herbicides (butyl ether of 2,4-dichlorophenoxyacetic acid (2,4-DA) and sodium salt of 2,4-dichlorophenoxypropionic acid (2,2-DPA)). Intragastric administration of the chlorophenoxy compounds resulted in significant activation of enzymatic microsomal oxidation systems. Parenterally administered preparations had no significant inducing effects. This shows the necessity of differentiating between detoxication mechanisms associated with different routes of exposure to harmful substances.

Study on potential atherogenic hazard of the pesticide acetochlor
Izučenie potencial'noj aterogennoj opasnosti pesticida acetohlora [in Russian]
Biochemical and cytological changes in the cardiovascular systems of rabbits associated with exposure to the pesticide acetochlor suggested that the compound is atherogenic. When administered jointly with cholesterol, its apparent atherogenic action was intensified. It is suggested that a safety factor of 100 be used when setting standards for autochlor residues.

Ultralow volume application of organophosphate concentrate in grain terminals: A new occupational health hazard
The introduction of ultralow volume (ULV) application of the organophosphate pesticide Fenitrothion in grain terminals presents a risk to workers of skin contact with concentrate. Blood testing, by the Ellman method, of a group of 5 grain terminal workers working on grain treatment showed a lowering of mean red blood cell cholinesterase (RBC ChE) activity to 23 units/gmHb (normal value 28-40) with a range of 16-29. The probable cause was identified as percutaneous absorption of Fenitrothion concentrate by workers using ungloved hands to clean blocked drip feed nozzles. Modification of work practices was followed by a rise of mean RBC ChE to 33.6 units/gmHb (range 32-36).

Effects of pyrethroid insecticides on subjects engaged in packing of pyrethroids
A health survey was conducted on 199 workers engaged in dividing and packaging pyrethroids. The subjects were exposed to fenvalerate at 0.012-0.055mg/m3 and deltamethrin at 0.005-0.012mg/m3 in the air with simultaneous skin contact for 0.5-4.5 months. Burning sensations and tightness or numbness on the face appeared in two thirds of the subjects and one third had sniffs and sneezes. Abnormal facial sensations, dizziness, fatigue, and miliary red papules on the skin were more evident in summer than in winter. Neither abnormalities in other organs or systems nor symptoms or signs of acute pyrethroid poisoning were found by interviews, examinations, and laboratory tests. There was no significant difference in plasma levels of NA, cAMP, and cGMP between the examined subjects and the control group. The urine concentration of fenvalerate in the study group ranged from 1.02 to 18.6µg/L; deltamethrin in the urine was present in trace amounts.

The determination of the odor threshold of Telone II soil fumigant by a new method
A method has been developed for the determination of the olfactory threshold of vapours and gases. It involves the dilution of a concentrated vapour or gas by a metering pump into an odour-free stream of air and an odour-free sampling system. Its advantage over other methods is the speed and accuracy with which odour thresholds can be determined. This method has been used to determine the odour of Telone II Soil Fumigant in air. In a population of 22 persons, the concentration at which odour was detected was 4.4 ± 3.1ppm (mean ± S.D.). This level is slightly above the current threshold limit value time-weighted average of 1.0ppm but below the short-term exposure limit of 10ppm.

An exposure characterization of a large scale application of a biological insecticide, Bacillus thuringiensis
Personal exposure and area air monitoring for Bacillus thuringiensis (Bt) was conducted to determine occupational and general public exposure potential to Bt. Portable sampling pumps with membrane filters (MF) were used to conduct the sampling. Analysis of the MF for Bt involved microbial culture techniques with the presence of toxin crystal formation confirming identification as Bt. This paper presents the exposure sampling results, discusses problems encountered when conducting microbial sampling with membrane filters, and discusses modifications to resolve the problems. Occupational exposure results ranged from 0 to 5600 colony forming units (CFU) of Bt/m3. General public Bt exposure results ranged from 0 to 1600CFU/m3.
