The objective of this study was to determine the spatial variation of particle-bound heavy metals in two communities with different industrial status in Nigeria’s Niger Delta Area. Fourteen ambient respirable particulate matter (PM10) samples 7 each from Eleme (highly industrialized) and Ahoada East (less industrialized) communities were collected according to standard methods using Anderson High volume sampler. Samples were analyzed for trace metals including Fe, Zn, Ni, Cd, and Pb using Atomic Absorption Spectrophotometer. Data were analyzed using descriptive statistics, Man Whitney U test and Spearman Rank Correlation all at P 10 levels were 1.83 times higher at Eleme than Ahoada East (P 0.05) and all the values were higher than both the USEPA and WHO limits. At Eleme spatial variation of PM10 was in the following order: APE5 > APE3 > APE7 > APE1 > APE4 > APE6 > APE2. Fe, Zn and Cd were higher at Eleme than Ahoada East and the EC/WHO values. Pb was poorly correlated with PM10 (r2 = 0.0819, P > 0.05) at Eleme. Communities with higher industrial presence in the Niger Delta are more exposed to particulate burden. Routine monitoring and strict adherence to regulatory limits must be enforced. 展开更多

Oil spills and gas flaring are major environmental problems and pose major source of adverse health outcomes to communities hosting oil wells and natural gas. As oil is spilt and gas is flared;air, soil and water in affected communities are polluted. Due to this, members of these communities are exposed to higher health risks. One vulnerable group that is usually affected in this regard is pregnant women. This systematic review identified and reviewed past studies on oil pollution and different types of pregnancy outcomes within a twenty-year gap, which is between 1999 and 2019. The review also discussed the exposure pathways of oil pollution. From a literature search on scientific databases conducted in August 2019 for articles relating to the objectives of the review, data were extracted from articles which met the inclusion criteria and contents were systematically analyzed based on types of pregnancy outcomes. This review showed that oil spill and gas flaring may put pregnant women at high risk of hypertensive disorders of pregnancy, gestational diabetes mellitus, maternal depression, miscarriages via three pathways. This review may be of some use in making policy in this area. 展开更多
