Occurrence and Human Health Risk Assessment of Phthalate Esters in Sediments from a Riverine in Southern Thailand

Phthalate esters (PAEs) are environmentally active organic pollutants that can cause endocrine disruption in humans. This study evaluated the human health risk associated with the dermal exposure to the levels of six common PAEs in sediments collected from U-Tapao River. A gas chromatograph/mass spectrometer (GC–MS) analytic method was used for the identification and quantification of PAEs. The human health risk was carried out using hazard quotient (HQ) and hazard index (HI).

Microbial Ecological Distribution of Marine Actinomycetes Isolated from L

Actinomycetes are threadlike or filamentous, Gram positive bacteria that form branching filaments with hyphae and asexual spores. The hyphae are usually septate or coenocytic in nature. The aim of this study was to investigate the microbial ecological distribution of marine actinomycetes isolated from the Lagos Atlantic Ocean, South West Nigeria. Marine (soil and water) samples were collected from about 10 m deep from Lagos Lagoon and Atlantic Ocean. Starch Casein agar was prepared aseptically.
