Bioaccumulation variability and human health risk assessment of organochlorine pesticides in edible fish and shellfish from the Northeast Bay of Bengal.

This study investigates the accumulation of organochlorine pesticides (OCPs) in edible fish and shellfish species from the northeast Bay of Bengal, emphasizing species variability, potential contamination sources, and associated human health risks. Samples of three finfish species (Tenualosa ilisha, Pampus argenteus, and Harpadon nehereus) and two shellfish species (Penaeus indicus and Scylla serrata) were collected from Cox's Bazar and Chattogram, key fishing zones in the Bay of Bengal coast of Bangladesh. Sixteen OCP compounds, including DDTs (p,p'-DDT, o,p'-DDT, p,p'-DDE, o,p'-DDE, p,p'-DDD and o,p'-DDD), Hexachlorocyclohexanes (HCHs; α-HCH, β-HCH, γ-HCH and δ-HCH), Heptachlors (HPTs; heptachlor, cis- and trans-heptachlor epoxide), DRNs (Aldrin, Dieldrin and Endrine) were analyzed using gas chromatography-tandem mass spectrometry (GC-MS/MS), with total concentrations ranging from 19.

Seasonal and diurnal variability of PM concentration along with the role of wind patterns over different locations of Delhi during the year 2018 to 2022.

The present study assesses the seasonal and diurnal variability of PM concentrations across different locations in Delhi, emphasizing the role of wind speed and direction. PM concentrations were analyzed using descriptive and statistical techniques, including ANOVA, Mann-Kendall trend, and correlation analysis. Data from the CPCB CAAQMS network at five distinct locations-Industrial, Commercial, Residential, Traffic, and Green areas-were examined from 2018-2022.

Assessing the vulnerability of Elasmobranch species in the Bay of Bengal: Insights from Lakkha gill net fishery of Bangladesh.

The elasmobranch population is declining in the Bay of Bengal of Bangladesh due to large-mesh gill net fishing, locally known as the Lakkha net, which primarily targets Indian threadfin (). This study was the first attempt to identify megafaunal bycatch in Lakkha fishing and assess its vulnerability using Productivity Susceptibility Analysis. A total of 40 elasmobranch bycatch species were identified, with sharks comprising 13 species from three families, while 27 rays belonged to six families, with the majority belonging to the Myliobatiformes order (60 %).

Size-specific variations in the length-weight relationship and relative condition factor of Hilsa shad () across its habitats in Bangladesh.

The length-weight relationship (LWR) and relative condition factor are widely used as the most important biological parameters to infer the growth pattern and well-being of fishes. The aim of our study was to investigate the growth parameters of the LWR in different growth phases of Hilsa (), a flagship species of Bangladesh, and compare its relative condition factors across its major habitats. Fish from various rivers in Bangladesh and the Bay of Bengal were sampled, their length-weight growth parameters were measured and subjected to statistical analysis with pooled data from other studies.

Pregnancy outcomes in women with gestational hypertension and preeclampsia at Paropakar Maternity and Women's Hospital, Nepal: A retrospective study.

Introduction: Gestational hypertension and preeclampsia are the most common types of hypertensive disorder in pregnancy and these conditions are associated with adverse maternal and fetal outcomes. This study aims to determine the differences in pregnancy outcomes in women with gestational hypertension and preeclampsia.

Methods: A retrospective study was done at The Paropakar Maternity and Women's Hospital, a tertiary level hospital, in the Kathmandu, Nepal.

Incidence and Risk Factors of Pre-Eclampsia in the Paropakar Maternity and Women's Hospital, Nepal: A Retrospective Study.

This study aims to determine the incidence of pre-eclampsia and distribution of risk factors of pre-eclampsia at Paropakar Maternity and Women's Hospital, Kathmandu, Nepal. A retrospective study included 4820 pregnant women from 17 September to 18 December 2017. Data were obtained from the medical records of the hospital's Statistics Department.
