OBJECTIVES To determine the relationship between semen quality and exposure to pesticide residues. METHODS A cross-sectional study was conducted among male farmers from 3 different communities in Sabah, Malaysia. A total of 152 farmers participated in this study of whom 62 farmers had been exposed to either paraquat or malathion or both to varying extents. Questionnaires were designed to reco...
the present study investigated construct equivalence of multiple choice (mc) and constructed response (cr) item types across stem and content equivalent mc and cr items (item type ‘a’), non-stem-equivalent but content equivalent mc and cr items (item type ‘b’), and non-stem and non-content equivalent mc and cr items (item type ‘c’). one hundred seventy english-major undergraduates completed mc ...
Human biomonitoring provides an efficient and cost-effective way to identify and quantify exposure to chemical substances, including those having deleterious eff ects on human organisms. Once the risk of hazardous exposure has been identified and the mechanism of toxic eff ects has been elucidated, an ultimate decision about how to reduce exposure can be made. A particularly high risk of exposu...
abstract this study investigated the predictability of variables from a motivational framework as well as individuals qualities to predict three non-linguistic outcomes of language learning. gardners socio-educational model with its measures has been used in the current study. individual qualities presented in this study include (1) age, (2) gender, and (3) language learning experience. the...
Pesticides usage in agricultural fields to control pests is extremely toxic to non target organisms like fish and affect fish health through impairment of metabolism, sometimes leading to mortality. Present study is a review of potential adverse effects of pesticides and pollutants in fish. Furthermore, the data generated could be useful in the environmental risk assessment of freshwater and ma...

background: pesticides are widely used in agriculture. excessive use of pesticides has health risk for human and threatens non-target organisms. this research aimed to determine lethal concentrations of malathion and hinosan for carassius auratus (5±1 gr) [mean ± sd]. methods: experiments were performed according to o.e.c.d for 4 days (96 h) and concentrations of 0, 1, 2, 4, 8 mg l-1 hinosan an...
BACKGROUND Pesticides are widely used in households to control insects and weeds. Several studies, over the past decades, have examined the possible relationship of serum concentration of organochlorine pesticides and the development of breast cancer. However, little data exists regarding an association between self-reported, residential exposure to pesticides and breast cancer risk. We, theref...
BACKGROUND An increased rate of non-Hodgkin's lymphoma (NHL) has been repeatedly observed among farmers, but identification of specific exposures that explain this observation has proven difficult. METHODS During the 1980s, the National Cancer Institute conducted three case-control studies of NHL in the midwestern United States. These pooled data were used to examine pesticide exposures in fa...
