“…Thus, pesticides can impair the neurogenic mechanisms involved in penile erection as well as other functions in the nervous systems. Although not directly shown for pesticides, induction of peripheral sensory-motor polyneuropathy and erectile dysfunction were diagnosed in a patient occupationally exposed to methyl bromide for 12 years [51] suggesting that neurologic mechanisms may be involved in erectile problems of the long-term exposed users.…”

There is also circumstantial evidence on the association of exposure to pesticides with chronic diseases like respiratory problems, dermal disorders, cardiovascular disease, nephropathies, chronic fatigue syndrome and aging [1]. Since health-workers are not adequately trained to identify adverse effects of pesticides [22,23] and because of the Abstract Background: The aim of the present study was to assess whether long-term exposure to pesticides is associated with adverse health effects in professional pesticide sprayers. Methods:The study was conducted in Lake Eyasi Basin and Ngarenanyuki in Arusha region, during the dry season in September-October 2013. In a cross-sectional study, 97 short-term exposed men with at most three months as professional sprayers were compared with 60 long-term exposed men with experience of at least five years as professional sprayers. The study participants were aged 18-30 years, drawn from the same source population and interviewed using semi structured questionnaire. The questions focused on spraying procedures and on present and recurrent medical history including presence of selected six known pesticide induced health conditions. Results:Organophosphates, carbamates, dithiocarbamates and pyrethroids were the most applied insecticides but also organochlorine fungicides and endosulfan were frequently applied. The majority of the sprayers reported unsafe pesticide use. Mean pesticide uses in litres, spray frequency per crop and per week were 637, and 1.3 respectively for about 270 days a year. Respiratory disease symptoms were the most frequently reported (46/157; 29.3%) followed by skin (27/157; 17.2%), and sight (24/157; 15.3%). When adjusted for age and other predictors, long-term exposed sprayers had significantly higher self-reported occurrences of peripheral neuropathy (OR=7.7, CI95%: 1.045-56.728, p=0.045) and respiratory disorders (OR=0.2, CI95%: 0.067-0.501, p=0.001) compared with short-term exposed. Furthermore, 10 sprayers, all long-term exposed reported poor libido and erection problems. Conclusions: These findings document lack of safety knowledge, safe pesticide management and the implementation of protective measures as well as suggesting that long-term exposure to pesticides increase the risk of experience disease conditions compared to short-term exposure.

BackgroundAlthough ozone-depleting methyl bromide was destined for phase-out by 2005, it is still widely applied as a consequence of various critical-use-exemptions and mandatory international regulations aiming to restrict the spread of pests and alien species (e.g. in globalized transport and storage). The withdrawal of methyl bromide because of its environmental risk could fortuitously help in the containment of its human toxicity.MethodsWe performed a systematic review of the literature, including in vitro toxicological and epidemiological studies of occupational and community exposure to the halogenated hydrocarbon pesticide methyl bromide. We focused on toxic (especially chronic) or carcinogenic effects from the use of methyl bromide, on biomonitoring data and reference values. Eligible epidemiological studies were subjected to meta-analysis.ResultsOut of the 542 peer reviewed publications between 1990-2011, we found only 91 referring to toxicity of methyl bromide and 29 using the term "carcinogenic", "neoplastic" or "mutagenic". Several studies provide new additional data pertaining to the mechanistic aspects of methyl bromide toxicity. Few studies have performed a detailed exposure assessment including biomonitoring. Three evaluated epidemiological studies assessed a possible association between cancer and methyl bromide. Overall, exposure to methyl bromide is associated with an increased risk of prostate cancer OR, 1.21; 95% CI (0,98-1.49), P = 0.076. Two epidemiological studies have analyzed environmental, non-occupational exposure to methyl bromide providing evidence for its health risk to the general public. None of the epidemiological studies addressed its use as a fumigant in freight containers, although recent field and case reports do refer to its toxic effects associated with its use in shipping and storage.ConclusionsBoth the epidemiological evidence and toxicological data suggest a possible link between methyl bromide exposure and serious health problems, including prostate cancer risk from occupational and community exposure. The environmental risks of methyl bromide are not in doubt, but also its health risks, especially for genetically predisposed subjects, should not be underestimated.

“…Two case reports describe the full spectrum of features of the intoxication (e.g., peripheral polyneuropathy, predominantly axonopathy, optic neuropathy, and cerebellar dysfunction) 52,53. There are two other case reports that describe a patient with peripheral polyneuropathy53 and resultant erectile dysfunction 54. A subject with polyneuropathy and cerebellar dysfunction showed a high cerebellar signal on MRI 55.…”

Occupational Neurologic Disorders in Korea

This article presents a schematic review of the clinical manifestations of occupational neurologic disorders in Korea and discusses the toxicologic implications of these conditions. Vascular encephalopathy, parkinsonism, chronic toxic encephalopathy, cerebellar dysfunction, peripheral neuropathy, and neurodegenerative diseases are common presentations of occupational neurotoxic syndromes in Korea. Few neurotoxins cause patients to present with pathognomic neurologic syndrome. Detailed neurologic examinations and categorization of the clinical manifestations of neurologic disorders will improve the clinical management of occupational neurologic diseases. Physicians must be aware of the typical signs and symptoms of possible exposure to neurotoxins, and they should also pay attention to less-typical, rather-vague symptoms and signs in workers because the toxicologic characteristics of occupational neurologic diseases in Korea have changed from typical patterns to less-typical or equivocal patterns. This shift is likely to be due to several years of low-dose exposure, perhaps combined with the effects of aging, and new types of possibly toxicant-related neurodegenerative diseases. Close collaboration between neurologists and occupational physicians is needed to determine whether neurologic disorders are work-related.
