“…The acute toxicity of OPs to target and non-target organisms has been studied extensively and is believed to result from irreversible inhibition of cholinesterase enzymes and subsequent elevations in synaptic acetylcholine levels (reviewed, Ecobichon, 1991). Among the variety of deleterious effects observed, cognitive symptoms associated with acute and/or repeated exposures to OPs can linger for months to years after exposure and include deficits in reaction time, as well as impairments of information processing, attention, learning, and memory (Amr et al, 1997; Dassanayake et al, 2007; De Silva et al, 2006; Salvi et al, 2003, Singh and Sharma, 2000; Steenland et al, 1994 and Stephens et al, 1995). It should be noted, however, that prior to the last several years, most of the published human literature on OP exposure and cognition described the consequences of relatively high-level exposures that also resulted in overt symptoms of cholinergic toxicity.…”

“…About half of the workers showed hyperreflexia, polyneuropathy, lumbar radiculopathy, and cervical myelopathy, as well as anxious mood, impaired attention, and psychomotor stimulation. EEG recordings showed abnormal findings in 17.4% of the subjects, mainly those with longer exposure [ 186 ]. These preliminary findings should invite further studies in this area.…”

“…Istnieją również doniesienia dotyczące zaburzeń czynności przewodu pokarmowego [15,36], nieswoistych objawów neuropsychicznych [37] i zaburzeń poznawczych [38] u pracowników zawodowo narażonych na cynk.…”

“…U stoczniowców z wieloletnim stażem (3-16 lat), pracujących w narażeniu na tlenek cynku w stężeniach nawet do 40-58 mg/m 3 (zwykle 3,8-25 mg/m 3 ), obserwowano gorączkę metaliczną, nieżyty górnych dróg oddechowych, dreszcze, kaszel, łzawienie, bóle głowy, nudności, zapalenie oskrzeli, leukocytozę i wzrost aktywności fosfatazy alkalicznej i aminotransferazy alaninowej [37,42]. U pracowników zawodowo narażonych na fosforek cynku obserwowano wzrost objawów neuropsychicznych, w tym lęk, bóle głowy, nerwowość, bezsenność i zmiany w zapisie elektroencefalograficznym.…”
