Brinjal (Solanum melongena L.) suffers from the attack of various pests throughout its different stages of the crop growth. Different insecticides are used to control these pest infestations. The application of these insecticides on brinjal plants may have an effect on their quality and nutritional parameters of fruit samples. In the present study effect of three different insecticides viz. Triazophos...
The present study deals with the estimation of antioxidant levels in blood of sewage and garage workers exposed to sewage water, washing water and vehicular air pollution compared with control group of population. The study areas were selected on the basis of drainage clearance and wards where workers are active as sewage workers. For garage workers, the garage selected was a large and busy one where...
This survey work summarizes the generation of indoor air pollutants (IAPs) through household products and activities and also the probable health symptoms of IAPs were discussed through questionnaire in the residential buildings of urban and semi urban area when compared to rural (control) area by door to door survey. The IAPs are categorized as physical, chemical and biological and surveyed as per...
Oryza sativa Linn. (rice) and Corchorus capsularis Linn. (jute) are the two major crops of the Bengal basin. Both rice and jute are generally grown in submerged flooded conditions, where arsenic bioavailability is high in soil. The consumers of the edible parts from both plants therefore face an inevitable source of exposure to arsenic, with consequent accumulation and toxicity. The objective of the...
As far as the detection of metal genotoxicity in fish is concerned, micronucleus (MN) test is considered an extremely suitable measure. In this study, frequencies of micronucleated erythrocytes were scored in peripheral blood of catfish, Heteropneustes fossilis (bloch) after acute in-vivo exposure of zinc at different concentrations (5, 10 and 30 ppm) in the laboratory condition. These three concentrations...
Arsenic (As) is a metalloid that causes severe water pollution due to its extravagant toxicity. Ceriodaphnia dubia, a freshwater crustacean, was selected as a model system to evaluate the degree of time and dosage dependent acute toxicity caused by pentavalent As [As(V)]. C. dubia were collected from a natural pond and treated with different concentrations of As(V) for 24 hours and 48 hours. For both...
This study aims to describe the hemoglobin Fannin-Lubbock-I, which has a rare mutation substituting the amino acid glycine with aspartic acid at codon 119 of the β-globin chain. A Bengalee Hindu Brahmin family from Kolkata in West Bengal was the focus of this study. Molecular analysis using ARMS-PCR and direct DNA sequencing revealed the presence of a GGC > GAC mutation in codon 119 of the β-globin...
The present study deals to know morphological damages of leaves of four selected plant species near roadside due to vehicular air pollution in Kolkata, India. The selected plant species are Ficus bengalensis, Ficus religiosa, Alstonia scholaris and Neolamarckia cadamba as these are very common as avenue trees. The study area was selected as per Low vehicular load (LVL) as control area, moderate vehicular...
Hereditary breast cancer constitutes 5–10% of all breast cancer cases. Inherited mutations in the BRCA1 and BRCA2 tumor-suppressor genes account for the majority of hereditary breast cancer cases. The BRCA1 C-terminal region (BRCT) has a functional duplicated globular domain, which helps with DNA damage repair and cell cycle checkpoint protein control. More than 100 distinct BRCA1 missense variants...
The tea mosquito bug (Helopeltis theivora Waterhouse) and red spider mite (Oligonychus coffeae Nietner) are the two major pests of tea (Camellia sinensis L.). Their intensity of infestation was increasing day by day in an alarming proportionand increasing resistance to pesticides constitutes a serious problem in North Bengal tea plantations, India. One of the insecticide resistance management strategies...
