Residents of Port Harcourt in Rivers State, Nigeria, and its environs have since the last quarter of 2016 been experiencing adverse environmental impacts of particle (soot) pollution. This “double air pollution burden”—the unresolved prevailing widespread air pollution and the “added” emergence of particle pollution considered an environmental health threat, led to protests against government inaction in some parts of the state. In February 2017, several months following the onset of the pollution, the government declared an Emergency, and set up a Task Force to investigate and find a solution to the problem. Global research suggests that particle pollution correlates positively with a range of morbidities and an increased risk of mortality among exposed populations. This underscores the need for rigorous implementation of existing environmental legislations established to protect the environment and public health. Nigeria’s rapid response to the 2014–2015 Ebola Virus Disease (EVD) and successful prevention of its spread provides some lessons for addressing such environmental health emergencies—strategic action, including effective environmental risk communication, environmental audit, and monitoring is key. Epidemiological studies of the affected population is imperative. A concerted effort by the Rivers State Ministries of Environment and Health, as well as academia and private organizations is required. Public service campaign in terms of government providing up to date information on the existing situation is required.

On 4 August 2011, United Nations Environment Program (UNEP) submitted an unprecedented, scientific, groundbreaking environmental assessment report (EAR) on Ogoniland to the Nigerian government. This was the outcome of a 14-month intensive evaluation of the extent of pollution. The intention was that UNEP’s recommendations would be implemented to restore the devastated environment, on the one hand, and on the other, counteract the numerous environmental health issues that have for decades, plagued Ogoniland. However, five years post-EAR, and despite the seriousness of the situation, no significant resolution has occurred on the part of the government or the Shell Petroleum Development Company (SPDC) or Shell. To date, millions of Niger Delta residents particularly those living in the oil-bearing communities, continue to suffer severe consequences. Although the assessment was conducted in Ogoniland, other communities in the Niger Delta are also affected. This article explores prevailing issues in the Niger Delta, using Ogoniland (a microcosm of the Niger Delta) as an example. A multidisciplinary approach for sustainable mitigation of environmental health risks in the Niger Delta is paramount, and environmental management tools offer valuable strategies. Adopting the UNEP’s recommendations for addressing environmental health problems requires implementing the environmental management/environmental management system (EM/EMS) model. However, the persistent lack of political will on the part of the Nigerian government, and the grossly nonchalant attitude by Shell remain major obstacles towards executing UNEP’s recommendations.

Industrial discharge of active pharmaceutical ingredients (APIs) into the environment in some middle- and low-income countries is not sufficiently regulated. The phytotoxicity of metronidazole (FLAGYL)—one of the most commonly used over the counter (OTC) antibiotics, to soybean (Glycine max) is investigated. Relative growth rate (RGR) expressed in gram per gram per day (gg−1d−1) was applied to plants destructively harvested at maturity (42 d), to determine the toxicological impact. Differences between mean RGR of the three groups were performed at 0.05 significance level. Multiple comparisons suggest that there was a statistical significant difference among mean RGR for all treatment groups. Metronidazole is toxic to soybean plants (Glycine max) based on dose-response criterion. There is a need to enforce treatment of pharmaceutical wastewater effluent by Pharmaceutical Manufacturing Companies (PMCs) before discharge into the environment.

The United States (US) occupies the frontline of events in modern history of environmental reform. The federal government through the National Environmental Policy Act (NEPA) of 1970 has not only established an environmental policy template for other nations to emulate, but has also produced a viable tool for regulating environmental quality (EQ) and delivering environmental justice (EJ)-Environmental Impact Assessment (EIA). However, environmental history provides evidence that political process and special interests govern the attainment of the EJ goal by way of inadequate adherence to the NEPA provisions. Public participation (PP) is a principal requirement for achieving EJ and constitutes a pivotal determinant of EIA outcome. Effective delivery of EJ through EIA does require complete compliance with NEPA stipulations. Furthermore, the responsible agency's resources in terms of both funding and commitment in allowing for the full representation of the opinions of residents within communities of concern (CoC) for environmental decision-making process are critically important. Public health research approach offers valuable tools towards achieving EJ goals. To approach this topic, first I provide a historical background on EIA and EJ from the standpoint of the NEPA. Second, I discuss the meaning and impediments of PP. Third, I examine two scenarios viz the Triassic Park Hazardous Waste Dump in Roswell, and the public hearing of the recent "controversial" oil and gas ordinance in Sandoval County, both in New Mexico. Finally, in the discussion part, I attempt to evaluate PP in both cases and suggest that none of the criteria seem to have been met in either case. I conclude that the Home State Rule designation of New Mexico State in terms of control over oil and gas activities places it at an advantage in benefitting from a fair PP.
