Soft-tissue sarcomas and exposure to chemical substances: a case-referent study.
110 patients with soft-tissue sarcomas reported to the cancer registry in 5 Swedish countries and 220 controls were studied. The risk ratio for soft-tissue sarcomas after exposure to phenoxy acids or chlorophenols was 5.1; for phenoxy acids 6.8 (4.2 when free from impurities) and for chlorophenols 3.3. The risk for workers exposed to 2,4,5-T and other phenoxy acids was 17.

Monitoring of grape harvesters for evidence of cholinesterase inhibition.
36 grape harvesters were studied for 6 weeks following reentry into vineyards sprayed with organophosphorus pesticides. Insignificant changes in blood cholinesterase activity were found. Some workers had very low levels of organophosphate metabolites in the urine throughout the study. Ethion dioxon was the only pesticide residue detected on the grape leaves. For practical reasons, it is recommended that monitoring studies rely more on urinary analyses than on venipuncture.

Effect of pesticides on working conditions in the weeding of sugar beet plantations
Rol' pesticidov v formirovanii neblagoprijatnyh uslovij truda pri propolke saharnoj svekly [in Russian]
Residual chlorinated organic pesticides and fertilisers in sugar beet plantation soil result, upon weeding, in the emission of toxic gases (hydrogen chloride, phosgene). These emissions start 18-20 days after application of the pesticides and continue for a week. With annual treatment the emissions start a week later and last for about 2 months. Maximum HCl emission occurs at higher atmospheric temperatures (during noon hours), and that of phosgene during hours of maximum UV irradiation (9.30-11am).

Occupational exposure to hexachlorocyclohexane - I. Body burden of HVH-isomers
Report on the examination of 57 production workers (mean exposure 10±9 years) with special regard to the levels of the isomers of HCH in blood in adipose tissue. Whereas the TLV was not exceeded in any of the workplaces, considerable concentrations of all HCH-isomers were found in the serum of the workers, and the concentrations in the adipose tissue were even 300 times higher. This indicates a pronounced accumulation of this substance in the human body, requiring biological monitoring of exposed persons by determination of the substance in blood.

Electromyographical neuromuscular synapse testing and neurological findings in workers exposed to organophosphorous pesticides
3 groups of agricultural workers consisting of a total of 195 men with moderate to intense exposure to Thimet and Avisol-DM pesticides and a control group of 26 workers with no history of pesticide exposure, were examined by electromyographical synapse testing. The neurological information recorded showed no significant difference between the pescitide-exposed and control group. The electrically evoked muscle potential series in exposed workers remained as constant as those recorded for the control group and neurological records showed no singificant deviations from normal for exposed workers. Electromyographical synapse testing and clinical neurological examination are not sensitive enough for early detection of latent pesticide intoxication.

Results of studies on 40 male and female workers (aged 20-50 years) who had worked between a few months and 5 years in zineb fungicide production. Prolonged exposure to zineb leads to deterioration in the phagocytic activity of polynuclear neutrophils and alkaline phosphatase activity, a reduction in the lysozyme levels and inhibition of cytochrome oxidase and peroxidase activity. The degree of change depends on exposure duration and the functional status of the hepatobiliary system.

Occupational hazards to pregnant women in the collaborative perinatal project.
Statistical analysis of the data resulting from examination of 23,961 pregnancies in which 4,575 women reported exposure to hazardous work conditions, indicated that women with a work experience of pesticide exposure had the most adverse reproductive history. More foetal deaths and stillbirths, more premature low-weight babies with low 5min Apgar scores, and more neurological abnormalities at 1 year and low intelligence quotient at 4 years were observed in this group. Occupational exposure to heat, chemicals and heavy lifting was associated with adverse pregnancy and pregnancy outcome experience. Occupational exposure to ionising radiation and animals did not show comparable effects.

Data for establishing the toxicity and hygiene characteristics of Pyrimor, a new pesticide
Materialy k toksikologo-gigieničeskoj harakteristike novogo pesticida pirimora [in Russian]
The toxicity and biological effects of Pyrimor (2-(dimethylamino)-5,6-dimethyl-4-pyrimidinyl N,N-diethylcarbamate) were studied in animals. The pesticide is highly toxic for rats and mice after intragastric administration, and moderately toxic for rabbits when absorbed through the skin. The threshold concentration for cats and rats is 2.6mg/m3 on acute exposure and 0.56mg/m3 on chronic exposure. Poisoning results above all by inhibition of cholinesterase activity. In view of the embryotoxic effects of the compound an exposure limit of 0.05mg/m3 is recommended.

Cancer and occupational exposure to arsenic: A study of pesticide workers.
Mortality and morbidity were studied in 1393 workers engaged in pesticide manufacture and packaging. There were 23 deaths from lung cancer and 2 from anaemias, a statistically significant excess. Lung cancer mortality was especially high in male production workers with presumed high arsenicals exposure. A dose-response effect was suggested. Exposed workers also had increased frequencies of keratoses and perforation of the nasal septum. Analysis of the lung cancer deaths and matched controls suggested a relationship between lung cancer and antecedent keratoses.

Disturbances of immunologic reactivity following exposure to pesticides in hothouses
O narušenii immunologičeskoj reaktivnosti organizma pod vozdejstviem pesticidov v uslovijah teplic [in Russian]
Female hothouse workers exposed to pesticides showed, despite the absence of clinical symptoms of poisoning, disturbances of immunologic homoeostasis (inhibition of non specific immunity and sensitisation to pesticides). The extent of these changes was proportional to length of employment in hothouses. There was a close correlation between indices of morbidity in the various groups, classified according to duration of exposure, and immunologic reactivity. Prophylactic measures are recommended, as from the first year of employment in hothouses, with emphasis on the distribution of vitamin preparations.

Hazards of crop spraying.
Inadequate decontamination of a crashed crop spraying aircraft resulted in symptoms of Metasystox 55 poisoning in 3 salvage engineers. Two fatal accidents were investigated. In both cases the toxic pesticide being sprayed was not a contributing factor to the accident. In the second case, water flushing of the aircraft did not remove the pesticide from the spraying pipes and salvage workers who handled the wings on a lorry, and who were not wearing waterproof overalls, came into contact with an aqueous solution of Metasystox. These workers suffered symptoms which included sore eyes, soreness of the throat and muscle spasms.

Council Directive of 15 July 1980 on the approximation of the laws of the Member States relating to straight ammonium nitrate fertilizers of high nitrogen content.
Directive du Conseil, du 15 juillet 1980, concernant le rapprochement des législations des Etats membres relatives aux engrais simples à base de nitrate d'ammonium et à forte teneur en azote. [in French]
This directive prescribes sampling methods for these fertilisers and rules for their transport, packaging, labelling, and analysis. Member states are required to adopt and publish the regulations necessary to comply with the directive, and to apply them from 1 Jan. 1984. The directive applies to ammonium nitrate fertilisers containing more than 28% by weight of nitrogen, which may contain inorganic additives or inert substances such as ground limestone, calcium sulphate, magnesium sulphate. Such inorganic additives must not increase the fertiliser sensitivity to heat or tendency to detonate. Where a member state has good grounds for believing that a fertiliser, although satisfying the requirements of the directive, constitutes a hazard to safety or health, it may temporarily prohibit the marketing of the fertiliser in its territory or make it subject to special conditions, but must immediately inform the other member states and the Commission of such action, for consultation. Annexes: characteristics of, and limits for these fertilisers; description of test of resistance to detonation.

Exploring citrus harvesters' exposure to pesticide contaminated foliar dust.
Studies on the measurement of dislogeable and available foliar dust in 32 citrus groves are reported. Dislogeable dust means surface or water-soluble residues; available dust is the most loosely adhering portion of the surface residues. Available foliar dust is a good predictor of total dust aerosols. Differences in foliar residue, airborne dust, and dermal pesticide measurements appear to be due to the wide range of particle sizes found (<1to>200µm). The airborne dust levels to which citrus harvesters are exposed in the dry season are generally above those permitted in other industries.

Sulfotep air levels were below the TLV of 15ppb following overnight ventilation. When ventilation was stopped they exceeded the TLV. Worker activity in the greenhouse significantly increased Sulfotep air levels. Ventilation throughout the day, and use of protective equipment, are recommended.

Acute phosphine poisoning aboard a grain freighter.
29 of 31 crew members became acutely ill after inhaling the fumigant phosphine aboard a grain freighter. The main symptoms were headache, fatigue, nausea, vomiting, jaundice, paraesthesia, ataxia, intention tremor, and diplopia. Phosphine gas had escaped from the holds through a cable housing located near the midships ventilation intake and around hatch covers on the forward deck. Details are given of medical history and physical examination, laboratory data, follow-up studies, and an environmental survey.

Assessment of occupational exposure to organophosphates in pest control operators.
Studies in 22 operators exposed to Vaponite, Diazinon, and Dursban are reported. Metabolites of all 3 pesticides were found in the 24h urine. There was a significant inhibition of plasma acetylcholinesterase, and no significant effect on mean red blood count. Personal protective equipment is required during handling and application of these pesticides.

Fact sheet on 2,4-D.
The toxicological background of 2,4-dichlorophenoxyacetic acid (2,4-D) is reviewed: acute toxicity; neurotoxicity; reproductive effects; oncogenicity; mutagenicity; epidemiology. Environmental exposure is considered. Conclusion: information on adverse health effects does not support regulatory action to remove 2,4-D from the market; the herbicide does not appear to present an imminent hazard when used according to instructions; more toxicological information on 2,4-D is required.

Evaluation of toxic hazards of organophosphorus and carbamate pesticides by the ACHOLEST method in an ethnic Japanese agricultural community (Atibaia)
Avaliação dos riscos de intoxicação por pesticidas organofosforados e carbamatos pelo método de ACHOLEST na Colônia agrícola japonesa de Atibaia [in Portuguese]
Using the ACHOLEST method to determine plasma cholesterase levels in 216 agricultural workers in an ethnic Japanese rural community (Atibaia, São Paulo, Brazil) the authors concluded that 11.1% of the group examined suffered from poisoning due to organophosphorus and carbamate pesticides. This percentage was considered to be relatively high. The influence of some variables was studied (type of crop or farming - flowers, strawberries, roses, peaches, vegetables, grapes; type of pesticide employed, concentrations and quantities used). Study of the suitability of this method: the results are encouraging, in view of its simplicity and low cost, and the possibility of distinguishing between individuals with different levels of enzyme inhibition.

Las intoxicaciones subagudas por plaguicidas agrícolas - Estudio de su problemática en el Levante español [in Spanish]
Report of a questionnaire survey involving 1,429 agricultural workers. Chemical pollutants seem to present the greatest hazards (organophosphorous and carbamate pesticides). Acute poisoning due to these substances has been well studied, but subacute or chronic disorders are not so well known: carcinogenic effects, chronic changes in the haematopoietic system, liver and kidney damage. Numerous statistical tables.

Comparative study of the intermittent and continuous effect of Ramrod herbicide
Sravnitelno izsledvane na intermitentnoto i monotonnoto dejstvie na herbicida Ramrod [in Bulgarian]
Experimental research on 3 groups of rats, subjected to 3 different types of exposure: daily administration of 70mg/kg for 4 months; daily administration of 140mg/kg on alternate weeks for 4 months; daily administration of 70mg/kg on alternate weeks for 8 months. The most pronounced liver function changes were observed in the animals receiving continuous administration. The 2 intermittent schedules gave rise to phases of adaptation; response to intermittent administration of 70mg/kg involved physiological compensation. It is preferable to use this pesticide (Ramrod, Propachlor) periodically in order to avoid chronic poisoning.
