A review of agricultural pesticide incidents in man in England and Wales, 1952-1971.
Analysis of the cases of poisoning attributed to pesticides in England and Wales during the period 1952-1971. There were 9 fatal cases, of which only 3 were occupational in origin. There were 222 non-fatal incidents affecting 296 persons. The main problems in the use of pesticides in England and Wales today are: illicit decanting of concentrate from the manufacturers' labelled containers; hoarding of incompletely used containers; disposal of empty containers; importation of pesticides in indadequately labelled containers.

Combined action of organophosphorus pesticides and increased environmental temperature in short-term inhalation studies in the rat
Über die kombinierte Wirkung von phosphororganischen Pestiziden und erhöhter Umgebungstemperatur in inhalatorischen Kurzversuchen an Ratten [in German]
The combined action of 3 different organophosphate pesticides and increased environmental temperature (35°C, 50% relative humidity) was investigated in subacute (8 days) inhalation experiments with male rats. In the first part of the study, toxicological aspects are discussed in relation to the following parameters: relative weight of organs, cholinesterase activity, total protein and protein fractions in serum, cell respiration in homogenised liver tissue, ACTH activity of the pituitary gland, body weight and body temperature. Most of the parameters examined revealed an increase in toxicity due to combined exposure. In the second part of the study, the results of histological, histochemical and morphologic studies are described: histology in lung, liver and thyroid, enzyme histochemistry in the liver, morphometry and storage of 131I in the thyroid. The results confirmed in general the increased effect of these pesticides at high environmental temperature.

The effect of maneb on intrauterine development of rats.
A single dose of the fungicide maneb (manganese diethyldithiocarbamate) administered to pregnant female rats during the phase of organogenesis induces nervous-system and skeleton malformations in the foetus (exencephalia, encephalocele, cheilognathopalatoschisis, phocomelia, amelia, ectrodactylism, microcaudia, acaudia, etc.). Doses corresponding to 2/3, 1/3 and 1/6 of the lethal dose 50 (6g/kg for adult rats) proved to be teratogenic. A dose corresponding to 1/12 LD50, both single and repeated, did not affect gestation.

Experimental inhalatory toxicity and substantiation of the maximum allowable concentration for some dithiocarbamates in the air of the working area.
Results of animal experiments carried out with a view to assessing the inhalation toxicity of zineb, maneb and mancozeb, and to establishing threshold limit values for long-term exposure. Toxic effects consisted of inflammatory, and sometimes ulcerative, changes in the trachea, inflammatory vascular damage to the lung which sometimes degenerated into emphysematous and atelectatic changes, hepatotoxic and nephrotoxic changes (severity according to concentration). Maneb and mancozeb, which contain manganese, have a more severe toxic action on the respiratory tract and other parenchymatous organs than zineb. The following threshold limit values are recommended: 1mg/m3 for zineb; 0.4mg/m3 for maneb; 0.5mg/m3 for mancozeb.

Exposure of spraymen to pesticides
Potential dermal and respiratory exposures, and the total exposure in terms of fraction of the toxic dose, were determined for 11 pesticides during orchard spraying with air-blast equipment. The highest total average exposure was just over 1% of the hourly toxic dose for workers applying the most toxic compound (carbophenothion). There was considerable variation in exposure to a specific pesticide depending on certain technical and environmental factors. Potential dermal exposure to each compound was much greater than potential respiratory exposure. There does not in normal circumstances appear to exist any serious risk of occupational poisoning.

Damage to health and protective measures when applying pesticides and herbicides
Yrkesskader og vernetiltak ved bruk av plantevernmidler [in Norwegian]
Following a classification of pesticides and herbicides into danger classes, and after reviewing the various toxic effects (including allergic reactions), the author briefly deals with herbicides (sodium, chlorate, DNOC, etc.), insecticides (pyridine derivatives, nitro compounds, nicotine preparations, chlorinated hydrocarbons, organo-phosphorous compounds) and fungicides (organo-mercury compounds). He sets out rules for the preparation of spray liquids and for their applications, and gives advice on the use of personal protective equipment, personal hygiene and good housekeeping. Other subjects dealt with are the storage of toxic substances, first aid in the case of poisoning, and the protection of the environment when applying pesticides and herbicides.

Determining atmospheric insecticide concentration by the filter method
Insektizid-Bestimmungen in atmosphärischer Luft mittels der Filtermethode [in German]
The advantages of the filter method for the quantitative determination of insecticides in air are presented. The results of studies with glassfibre filters are discussed. Gas chromatography with an electron-capture detector is used for analysis purposes. One must expect a high loss of material due to the amount of air passing through the filter. Although this loss is probably lower in practice, great care should be taken in the interpretation of results obtained with this method.

The value of enzyme activity changes in assessing chlorinated cyclodiene pesticide toxicity
Dynamika zmien enzýmovej aktivity pri hodnotení toxicity pesticídov na báze chlórovaných cyklodienových zlúčenín [in Czech]
Dieldrin and aldrin in an oil solution were administered per os, at a rate of 7 and 12mg/kg body weight per day for 4 weeks, to 2 groups of rats and at a rate of 40mg/kg (2/3 of the LD50) in a single dose to a third group. In each case there was an increase in glutamic pyruvic transaminase and serum aldolase. Maximum activity was observed 72h following administration of the single dose and the 7th day following administration of repeated doses. After 28 days, enzyme activity had returned to normal. On the basis of these results, the author considers that glutamic pyruvic transaminase and serum aldolase activity may be employed as a useful criterion for evaluating the acute and sub-acute toxicity of the substances in question.

Hexachlorobenzene and other organochloride pesticides in human blood
The concentration of organochlorine compounds with pesticidal activity was determined in the whole blood from 237 subjects in a study to determine normal background levels of hexachlorobenzene (HCB). 185 of the group had some occupational exposure to these compounds (pesticide sprayers, greenkeepers, pesticide production or packaging workers), and 52 people had no known exposure. None of the subjects showed any apparent signs of intoxication. Nearly all blood specimens examined contained DDT, HCB and other commonly found pesticides in amounts comparable to the levels reported in studies in other countries. However, the majority of specimens contained the fungicide hexachlorobenzene, the presence of which in blood had not been reported previously.

Electrometric cholinesterase methodology in the monitoring of biocide workers
A group of 12 men working daily or weekly with a mixture of pesticides (benzene hexachloride, lindane, chlordane, malathion, pyrethrum and occasionally dimpylate) were monitored as regards cholinesterase activity in blood by using 2 different methods. A rapid electrometric method was used for the determination of butyrylcholinesterase and acetylcholinesterase in small capillary blood samples, and a semi-quantitative method (Merckotest) was selected for comparison. The procedures are described, and the results presented and interpreted.
