Persistent organic pollutants (POPs) include lipophilic legacy POPs and the amphiphilic perfluorinated alkyl acids (PFAAs). They have long half-lives and bioaccumulate in the environment, animals and human beings. POPs possess toxic, carcinogenic and endocrine-disrupting potentials. Endocrine-disrupting chemicals (EDCs) are compounds that either mimic or block endogenous hormones and thus disru...

Ground-level ozone is a secondary air pollutant that formed by chemical reactions between precursors, including nitrogen oxides (NOx) and hydrocarbon (HC). Highway traffic, which can be controlled traffic operational strategies, one of the main sources atmospheric NOx HC. Managed-lane pricing popularly used freeway management approaches, while its impacts on ground-level ozone-related vehicle e...

Basing on the experimental study of fuel consumbtion in World-wide Harmonized Light-duty Test Cycle (WLTC ), this paper conducted effects using different immersion temperature consumption a light-duty gasoline vehicle. The mainly studied first phase WLTC with three gaseous pollutant emissions: carbon dioxide, monoxide and unburned hydrocarbon(CO2, CO HC )which is measured to caculate Gasoline V...

The site of the 2000 Olympic Games (Sydney Olympic Park (SOP), Sydney, Australia) was contaminated by persistent organic pollutants (POPs) prior to remediation in the 1990s. This study investigates the bioactivity of POPs in the sediment and water of wetlands across SOP by in vitro 2,3,7,8-TCDD equivalence (TCDDeq) measurement (H4IIE cell line bioassay). Further, it examines whether disturbance...

BACKGROUND Persistent organic pollutants (POPs) such as polychlorinated dibenzo-p-dioxins/furans, polychlorinated biphenyls (PCBs) and organochlorine pesticides can cause a series of adverse effects on e.g. reproduction in animals and humans, many of which involve the aryl hydrocarbon receptor (AhR). The aim of the present study was to compare the integrated serum level of AhR mediated activity...

Abstract Hydrocarbon pollution, especially polycyclic aromatic hydrocarbons which are toxic, carcinogenic and mutagenic in the sea, has a negative impact on biota must be controlled. Identification isolation of bacteria that have potential to degrade sea need done overcome hydrocarbon pollution. The methods used include quantitative test for biodegradation capacity, identification bacterial spe...

Passage of the 1990Amendments to the Clean Air Act made it clear that maximum available control technology (“MACT”) regulations on the emission of hazardous air pollutants (“HAPS”) from process heaters and industrial boilers, used extensively in the petroleum and petrochemical industries, would be promulgated under congressional mandate by the U. S. Environmental Protection Agency in the year 2...

TCDD (2,3,7,8-tetrachlorodibenzodioxin), a highly persistent environmental pollutant and a human carcinogen, is the ligand with the highest affinity for the Aryl Hydrocarbon Receptor (AhR) that induces via the AhR, xenobiotic metabolizing enzyme genes as well as several other genes. This pollutant elicits a variety of systemic toxic effects, which include cancer promotion and diverse cellular a...

Abstract The activities of the petroleum mining industry in Indonesia have caused many problems by producing hazardous waste pollution that would produce dangers for plants, animals or human lives. One technique to recover environmental situation is through land farming technique. purpose this study overcome crude oil environment using biotechnology method process enzymatic bioremediation. para...
