Dong Nai river is known for its important role in the economic development of Vietnam such as the main water supply for the South-East region of Vietnam, hydropower development, especially capture fishery. One of the problems to be concerned is the fishery resources and their impact on Dong Nai river. Phytoplankton has been known as an important component involved the food chain, as well as a reflection factor of the water environment quality. The study of phytoplankton will contribute important information in the evaluation of the biodiversity and environmental quality in Dong Nai river. Therefore, study was conducted to evaluate the variation of phytoplankton density in Dong Nai river. The research on the phytoplankton density was studied from 32 samples collected in March, June, August and December 2014 at 8 locations of Dong Nai river (from Song Be river to An Hao wharf). The species compositions of phytoplankton included 145 taxa of Cyanophyta, Chrysophyta, Bacillariophyta, Chlorophyta, Euglenophyta, and Dinophyta. The dominant genus were Staurastrum, Cosmarium, and Melosira. The phytoplankton density ranged from 10,709 to 201,258 individuals.L. The densities in March and June were higher than those in September and December.

A study has been conducted to evaluate some metal concentration of spicy from local market of Chittagong metropolitan city, Bangladesh. Total 30 spicy samples of red chili or chili red, coriander, turmeric were collected from five different spot (Khatungonj, Chakbazar, Muradpur, Baluchora, Amanbazar) under Chittagong metropolitan city and metal as Zn, Cu, Cr, Mn, Fe concentration was measured. Metal concentration in red chili, coriander, turmeric were found as increasing order as CuKhatungonj>Muradpur>Baluchora>Amanbazar,Khatungonj>Chakbazar>Amanbazar>Muradpur>Baluchora,Khatungonj>Chakbazar>Baluchora>Amanbazar>Muradpur,Khatungonj>Chakbazar>Muradpur>Amanbazar>Baluchora,Khatungonj>Chakbazar> Baluchora >Amanbazar>Muradpur respectively. So, Spicy of Khatungonj was the highly contaminated with metal followed by chakbazar spicy and least metal concentrated spicy was in Amanbazar at Chittagong city. According to WHO (World Health Organization), Cr and Fe concentrations exceeded the permissible limit of heavy metals in spicy but other metal concentrations was within tolerable limit. The current research’s findings will convey a strong message for the government body, policy maker to establish rules and regulation in order to protect food chain contamination, environment pollution and will be helpful for public awareness. An immediate attention from the concerned authorities is required in order to protect food chain contamination and environment pollution.
