Pine bark beetle insecticide treatment plots were established on the Ocala National Forest, in central Florida. Each plot consisted of five sand pine, pinus clausa (Chapm. Ex. Engelm) Vassey ex. Sarg., trees treated with either 0.5% lindane (benzene hexachloride) or 2% chlorpyrifos (O,O-diethyl O-(3,5,6-trichloro-2-pgridyl) phosphorothioate). After 4 months, mean residue levels ranged from 0.32...

Lindane, T-l,2,3,4,5,6-hexachlorocyclohexane (HCH), has been used, per s__eeor as the active ingredient of BHC (benzene hexachloride, in agriculture and public health for nearly three decades as a soil insecticide, foliar spray, seed dressing and for protection of stored grains. Many reports in the literature have alluded to the persistence of lindane in soil, its translocation into crops and c...

Fifteen Grimaud female hybrid rabbits, 135 days old and weighting an average of 3.74+/-0.01 kg each, were administered an oral dose of 1 mg x kg(-1) body weight of Lindane during gestation and lactation period. Fertility rate, libido, volume of ejaculate, concentration and morphology of spermatozoa were investigated to test the effects of the treatment on reproductive traits of first generation...

The neurotoxic agent lindane was tested for its ability to alter the rate of ultrasonic isolation calls of suckling rats. Doses that did not produce any sign of convulsant activity significantly increased the number of calls and the cumulative time of calling in male pups. At days 10-13 of age after a single dose of 20 mg/kg lindane, animals showed more than twice the control call values. After...

Reproductive health problem is more common nowadays and various causes like nutritional defect, socio-economic problems, life style changes are reason for that, among those reason, one important factor is environmental factor. In this study, the pesticide, Lindane is used to induce reproductive toxicity and the levels of male reproductive hormone, antioxidant and histopathology of rat testis wa...

The oxidation of lindane is investigated by photooxidation and photocatalytic procedures using solar light irradiation. The photocatalyst used in photocatalysis is Degussa P25 TiO2. The degree of oxidation is followed by chemical oxygen demand (COD) measurements. The oxidation process is carried out at different initial concentrations of lindane varying from 0.05×10 M to 1.0×10 M. The photooxid...

Although worldwide concerns have emerged about environmental factors that display carcinogenic and reprotoxic effects, little is known about the mechanism(s) by which these chemicals alter testicular function. Using the 42GPA9 Sertoli cell line, we recently reported that one widely used lipid-soluble pesticide, Lindane impairs gap junctional intercellular communication by promoting the intracel...

Lindane is losing much of any luster it once had. The pesticide, once widely used to kill lice and a variety of pests that attack agricultural products, livestock, and trees, has slowly been eliminated from many applications since the mid-1970s. As long ago as the early 1980s, three U.S. organizations petitioned the U.S. Food and Drug Administration (FDA) to ban lindane following an FDA doctor’...

Environmental contaminants possessing hormonal activity have long been suspected of playing a role in cancer causation. What is unclear is whether such agents elicit their effects through genotoxic and/or epigenetic mechanisms. gamma-Hexachlorocyclohexane (gamma-HCH, lindane) was tested in the 10(-12)-10(-4) M range. Chromosomal damage in MCF-7 breast cells and PC-3 prostate cells was assessed ...

Many vespertilionid bats roost in proximity to roo®ng timbers and are therefore potentially exposed to organochlorines used as wood preservatives. Organochlorines elevate metabolic rate (MR) in some vertebrate species and any such e€ect in bats may threaten survival. The aim of this study was to determine whether sublethal exposure to lindane a€ected the body mass, food intake and MR of pipistr...
