Control of substances hazardous to health in fumigation operations; Control of Substances Hazardous to Health Regulation 1988 [United Kingdom] - Approved Code of Practice
This booklet contains the Approved Code of Practice (effective 1 Oct. 1989) and 19 Regulations (applying to all fumigant gases; special duties are also imposed on the users of the more commonly used fumigants - methyl bromide, hydrogen cyanide, ethylene oxide and phosphine). The Code was approved under Section 16 of the Health and Safety at Work Act 1974 for the purpose of providing practical guidance with respect to the provisions of the Control of Substances Hazardous to Health Regulations 1988. It applies to fumigant operations whether undertaken in the open air, in temporarily created containment or in purpose-built fumigation or sterilisation chambers or enclosures. It does not apply to the use of vapours, fogs, fumes and smokes for the purpose of pest control, the use of which should follow the Approved Code of Practice, "The Control of Substances Hazardous to Health: Control of Exposure to Pesticides at Work" (in preparation).

Assessment of the risk of exposure to pesticides by farmers in Quebec
Mesure du risque d'exposition aux pesticides pour les producteurs agricoles du Québec [in French]
Findings of a questionnaire survey show that the consulted workers safely executed only 42% to 60% of the analysed tasks even though their level of awareness and judgement of safe work methods is approximately 70% to 86%. It seems that agricultural producers have a high risk level of exposure to pesticides, not because of their lack of awareness of the existence of safe work methods but rather because of their lack of motivation to implement them. It is assumed that producers mainly need to be informed of the real toxicity of pesticides in order to accurately gauge the risk associated with the use of these products.

Soft tissue sarcoma risk in Swedish licensed pesticide applicators
Two Swedish studies have suggested that exposure to phenoxy acid herbicides may cause soft tissue sarcoma. This association has been subsequently investigated in a number of epidemiologic studies. Results are inconsistent. In this study the risk of soft tissue sarcoma in a cohort of 20,245 Swedish pesticide applicators, of whom 72% were estimated to have been exposed to phenoxy acid herbicides, was analysed. The cohort was observed by means of the Swedish Cancer Register from date of license until Dec. 31, 1984, or until death if it occurred prior to that date. The mean follow-up time was 13.9 years. Seven patients with soft tissue sarcoma were observed compared with 7.7 expected on the basis of the incidence in Sweden. The relative risk was found to be 0.9 (95% confidence interval, 0.4 to 1.9). This finding is consistent with the hypothesis that exposure of phenoxy acid herbicides does not increase risk of soft tissue sarcoma.

A second follow-up of mortality in a cohort of pesticide applicators
A cohort of 16,124 male pesticide applicators was matched with Social Security Administration and National Death Index (NDI) files through 31 December 1984. In all, 1,082 deaths were ascertained, and death certificates were obtained for 994 (92%). The standardised mortality ratio (SMR) for all causes of death was 98. Although a number of specific causes of death showed SMRs significantly below 100, one category of cause of death showed a significantly elevated SMR - cancer of the lung, with an SMR of 135. Termite control operators (TCO) - the group with the greatest likelihood of exposure to chlordane and heptachlor - had an SMR for lung cancer of 97, compared with 158 for other pesticide operators. The excess of lung cancer in the non-TCO workers was limited to operators employed as such for less than 5yrs.

Health effects among workers involved in the manufacture of hexachlorocyclohexane
Forty-five male workers exposed to hexachlorocyclohexane (HCH) during its manufacture were studied and compared with 22 matched controls. Twenty-one of the exposed workers worked in packaging and manual transport of HCH. Twenty-four other exposed workers were plant operators. Exposure was mainly through skin. Results indicate that the neurological symptoms reported were due to recent exposure to HCH and were related to the intensity of exposure. An increase in leucine aminopeptidase, ornithine carbamyl transaminase, 5'nucleotides and immunoglobulin M levels among the exposed workers is suggestive of some degree of liver damage. A significant increase in total blood HCH and its α, β and γ isomers was also observed in these workers. In spite of pronounced exposure to the α, β and γ isomers of HCH, signs of severe health impairment were not observed. Further biological monitoring needs to be carried out among such workers exposed to HCH.

Cancer risk of pesticides in agricultural workers
This report discusses some of the inherent limitations of cancer studies in animals and humans and presents a qualitative carcinogen risk assessment of a number of pesticides based on the judgement of national and international authorities who have reviewed the available experimental and epidemiologic evidence. A large number of pesticidal compounds have shown evidence of genotoxicity or carcinogenicity in animal and in vitro screening tests, but no pesticides - except arsenic and vinyl chloride (once used as an aerosol propellant) - have definitely been proved to be carcinogenic in man. A resolution by the Council on Scientific Affairs calls for the American Medical Association, through its scientific journals and publications, to alert physicians to the potential hazards of agricultural pesticides.

Smouldering of phosphate fertilisers
Sigaroobraznoe gorenie fosfornyh udobrenij [in Russian]
Twenty-one fertilisers were tested for their ability to support smouldering combustion and the results were tabulated. Most nitrate-containing fertilisers supported slow burning. Those containing manganese and cobalt were more likely to burn than fertilisers of otherwise identical composition that lacked those elements. Iodine, boron, zinc and molybdenum had no effect. The nitrate-free fertilisers tested absorb heat on decomposition and so do not support slow burning.

Farming and malignant lymphoma in Hancock County, Ohio
A case-control study was conducted using death certificate records of white male Hancock County (Ohio, USA) residents for 1958-83 which revealed raised death rates for non-Hodgkin's lymphoma (NHL) and Hodgkin's disease (HD). There were 61 cases of NHL, 15 cases of HD, and 304 control subjects. Cases and controls were compared with respect to adjustment for age at death and year of death. Summary odds ratios (OR) and 95% confidence intervals (CI) were calculated. NHL was associated with the occupation of farmer (OR=1.6; CI=0.8, 3.4; observed number of exposed cases (Obs) = 15). The association was restricted to 1958-75 (OR=2.1; CI=0.9, 4.8; Obs=13). The 3 cases of HD among farmers occurred in a cluster in the 15-64 age range during 1958-63 (OR=21.2). This small study adds to the growing body of reports linking farming and malignant lymphoma, particularly NHL.

Risk of malignant lymphoma in Swedish agricultural and forestry workers
The risk of malignant lymphoma after exposure to phenoxy acid herbicides was studied in 354,620 Swedish men who were employed in agriculture or forestry. The cohort was divided into subcohorts and compared with 1,725,645 Swedish men having other economic activities. All were followed up between 1961-1979. Non-Hodgkin lymphoma was found in 861 men in the study cohort. The relative risk was not significantly increased in any subcohort and showed no time-related increase in the total cohort or any subcohort. Hodgkin's disease was found in 355 men in the study cohort. Relative risks significantly higher than unity were found among fur farming and silviculture workers where they were 4.45 and 2.26, respectively. All 5 cases in the former group were engaged in mink farming. A time related rising trend in relative risk was found in the silviculture subcohort.

Farming and exposure to chemicals in male lung cancer patients and their siblings
Retrospective questionnaire study concerning farming and exposure to chemicals of 165 male lung cancer patients (mean age 64.2) and 165 closest in age male siblings (mean age 64.5). The patients were diagnosed as having primary lung cancer between January 1, 1979 and November 1, 1983. Among the lung cancer patients, 38.5% had a same-sex sibling eligible for inclusion and of these, 62.0% responded to the questionnaire. Mean peak years of smoking for patients was 41.0 (n = 135) and among the siblings 36.9 (118) (p<.002). The occupation of farming was present in 47.8% of 163 patients with known occupations as compared to 37.6% of 155 siblings with known occupations (not significant). Patients were consistently exposed more frequently to herbicides (p = .05), grains (p<.015), and diesel fuels (p<.005), and were consistently exposed to greater numbers of chemicals than were siblings (p<.005). These findings raise the possibility that, in addition to smoking, farming and related exposures could be implicated in the aetiology of lung cancer in men.

Biological indicators for the assessment of human exposure to industrial chemicals: Aldrin and dieldrin, arsenic, cobalt, endrin, vanadium
The available data on the human health effects, metabolism and biological indicators of these substances are reviewed. Conclusions reached: determination of the concentration of dieldrin in blood is the most relevant test for assessing aldrin-dieldrin exposure and dieldrin body burden; determination in urine may be used for monitoring exposure to arsenic and vanadium; occupational exposure to cobalt can be measured by measuring its concentration in ambient air and, for soluble cobalt compounds, also by measuring the concentration of the metal in urine and blood; the concentration of endrin in blood is an indicator of short-term over-exposure to endrin, while urinary concentration of the major endrin metabolite is used for the measurement of normal low occupational exposure.

Bromsulfalein clearance in persons in professional contact with pesticides
Klirăns na bromsulfaleina u lica văv profesionalen kontakt s pesticidi [in Bulgarian]
In 46 persons, bromsulfalein clearance was followed during a season of work with pesticides. The mean value of bromsulfalein clearance (8,91%) was lower than that of a referent group of healthy persons (14,5%). In 14 of the exposed group the clearance values were under 10%. The changes in clearance do not correlate closely with other indices of liver function. Bromsulfalein metabolism, like pesticide metabolism, probably involves the glutathione-S-transferase system. This makes the measurement of bromsulfalein clearance useful in assessing the effect of pesticides on persons who work with them.

Basis for maximum allowable concentration for chrysanthemic acid, chrysanthemic ethyl ester and chrysanthemic chloranhydride in workplace air
Materialy k obosnovaniju PDK hrizantemovoj kisloty, ėtilovogo ėfira i hlorangidrida v vozduhe rabočej zony [in Russian]
Chrysanthemic acid, ethyl chrysanthemate and chrysanthemoyl chloride - intermediates in the industial synthesis of the new insecticide neopyamine - were studied in animal experiments. The compouds are of moderate toxicity on intragastric administration, are only slightly absorbed by the skin, produce moderate irritation and do not provoke sensitisation. Of the 3, chrysanthemoyl chloride was the most toxic (LD50 = 160mg/kg, mouse) but was not embryotoxic or teratogenic. Maximum allowable concentrations of 10mg/m3 for chrysanthemic acid and ethyl chrysanthemate and 2mg/m3 for chrysanthemoyl chloride are proposed.

Medical examinations of 206 mechanics aged 20-50 years occupationally exposed during 4 years to various groups of pesticides revealed morphocytochemical changes in neutrophilic leukocytes which were characterised by toxic granularity, decreases in glycogen and lipid content, inhibition of redox enzymes (myeloperoxidase and acid phosphatase), and increase in alkaline phosphatase activity. A decrease in acid phosphatase and increases in lactate and succinate dehydrogenesis were also identified in lymphocytes. These changes in peripheral leukocytes show the high sensivity of the blood to pesticide exposure and can be used as diagnostic criteria.

Chromatographic methods of determination of nitrogen and phosphorus-containing pesticides in air
Hromatografičeskie metody opredelenija azot-fosforsoderžaščih pesticidov v vozduhe [in Russian]
Conditions were determined for the collection, separation and quantitation of 4 organophosphorus pesticides that may be present in workplace air. 20L of air is drawn through a paper disc backed by polyurethane foam. The disc and foam are extracted with acetone and the extract is concentrated. A sample of the concentrate may be subjected to gas chromatography on a column of 5% Se-30 on Chromaton N-AW at 190 or 210°C (flame photometric or thermal ionisation detector), or to thin-layer chromatography on silica gel with hexane-acetone mixtures; after visualisation of spots with Dragendorff's reagent or silver nitrate, the diameters of the spots are measured. The limit detection in air of actellic, pirimiphos ethyl and pyridafenthion is 0.1mg/m3; for hostaquick, 0.2mg/m3. Error limits are 15.5-19.6%.

Toxicology of β-dihydroheptachlor (Dilor) and regulation of safe exposure levels
Toksikologija β-digidrogeptahlora (dilora) i reglamentacija bezopasnyh urovnej ego vozdejstvija [in Russian]
Animal experiments to study the toxic properties of Dilor were carried out. Like other organochlorine pesticides, Dilor affects the nervous system, upsets the protein synthesis, carbohydrate metabolism and detoxification functions of the liver, and thus produces disorders of protein carbohydrate and lipid metabolism. Dilor is a chemical of low toxicity with moderate cumulative effects. The results obtained were used as a basis for a MAC for Dilor in workplace air: for industrial premises 0,2mg/m3, in agriculture 0,5mg/m3.

Minimum waiting periods for safe work with phosdrin and vydate in greenhouses
Minimalni srokove za bezopasna rabota s fosdrin i videjt v oranžerii [in Bulgarian]
Degradation dynamics of vydate and phosdrin were followed on treated greenhouse flowers. Vydate reduces plasma and erythrocyte cholinesterase activity (ChEA). It is a pesticide that degrades slowly. Phosdrin degrades faster and the amount when no effect on ChEA is observed (0.25mg) allows one-hour exposure of workers (weeding and picking carnations) as early as the first day after spraying. Minimum waiting periods are proposed for work in greenhouses after spraying: 3 days for phosdrin and 4 days for vydate.

Study on renal function in chronic peroral propineb intoxication
Proučvane na băbrečnata funkcija pri hronična oralna intoksikacija s propineb [in Bulgarian]
Rats were perorally treated with propineb in doses of 425 and 34mg/kg body mass (1/20 and 1/125 LD50), two times weekly for 4.5 months. Renal function was evaluated in terms of: clearance of endogenous creatinine, urea, sodium and potassium, chlorides in serum, serum osmolarity, clearance of free water and percentage of excreted versus filtered sodium. Decreased glomerular filtration and free water clearance, and increased sodium excretion were observed. Morphological studies established that functional changes precede morphological ones, and should be given consideration in the evaluation of pesticide residues in foods and in hygienic standard-setting.

Studies on acute and subacute oral toxicity of Sandofan C-50
Izsledvane na ostrata i podostrata oralna toksičnost na Sandofan C-50 [in Bulgarian]
Sandofan C-50 is a preparation containing 40% copper oxychloride and 10% oxadixyl. The acute oral LD50 for albino rats (840mg/kg) puts the preparation into group III (moderately hazardous). At doses of 1/20 LD50 (42mg/kg) and 1/50 LD50 (16.8mg/kg) in 30-day experiments, there was no cumulative effect. Moderate signs of general toxic action were seen at the higher dose (42mg/kg): elevated activities of several dehydrogenases in blood and brain tissue, but there was no change in the general physical status and behaviour of the animals. The dose of 16.8mg/kg was inactive under the conditions of the 30-day experiments.

Comprehensive study of the effects of agricultural chemicals on human bodies
Nōgyō kagaku busshitsu ni yoru jintai e no eikyō ni kansuru sōgōteki kenkyū [in Japanese]
This is a report on the findings of a comprehensive study done by the Pesticide Poisoning Study Team of the Japanese Association of Rural Medicine in 1983-85. In the three years, 416 cases were treated at 35 medical institutions. In comparison with past findings, there was no decrease in accidents, the incidence was greatest among people in their fifties and herbicides were the principal problem. As regards organochlorine pesticides in the fat tissue of human bodies, 0.3ppm of total DDT and 0.2ppm of total BHC were detected. The amount of mercury in hair was 4.4-5.8ppm for men and 3.2ppm for women. In experimental studies on the chronic effects of pesticides, animals fed with low-protein forage were readily poisoned by organophosphorus compounds. Among experimental animals painted with paraquat or exposed by inhalation, it was detectable for 17 days in excreta in the former case and for 10 days in the latter. No lung fibrosis was observed.

Determination of the waiting period for safe work after the application of methyl parathion under field conditions
Opredeljane na minimalen srok za bezopasna rabota sled prilagane na metilparation pri polevi uslovija [in Bulgarian]
Workers spent 1h per day in contact with vegetables that had been treated with a 0.1% aqueous emulsion of methyl parathion. The pesticide is a strong inhibitor of cholinesterase activity - induces up to 50% inhibition of plasma ChEA on the first day after spraying. The rate of disappearance of methyl parathion from washings of workers' hands (daily samples for 7 days) showed that the compound degrades slowly. The minimum waiting period for safe work with methyl parathion under field conditions was determined to be 7 days.

Health effects of pesticides: A review of epidemiologic research from the perspective of developing nations
Acute poisoning among pesticide applicators is still a prominent health hazard in rural areas in developing countries. Data from China show that with a well organised grass-roots-level network of primary health care services, poisoning episodes can be prevented through the dissemination of information on the hazards and provision of prevention training courses. Among pesticide manufacturing workers, especially manual packers of organophosphorus insecticides, there is suggestive evidence of subacute poisoning resulting from continuous low-level exposure. Present evidence indicates a positive association between excess human cancer and the use of chlorinated hydrocarbon insecticides, between soft tissue sarcoma, non-Hodgkin's leukaemia, and lymphoma, and phenoxyacetic and chlorophenol herbicides. Further study of the cause of subacute poisoning now requires analytical investigation.
