The cement industry though the backbone of modern construction and civilization is associated with the emission of diverse atmospheric pollutants with numerous attendant effects on the balance of ecosystem, human and environmental health and the global climate in general. Despite the huge advantages derivable from the industry, exploitation and processing of cement must be done in a sustainable manner to prevent irreversible damage to human, animal and vegetation health as well as the environment. Research papers were reviewed from different databases like ScienceDirect, ResearchGate, Google scholar, and Scopus the chief air pollutants are the inorganic gaseous emissions (carbon dioxide (CO2), carbon monoxide (CO), oxides of nitrogen (NOx), oxides of sulphur SO2), particulates of various size ranges and elemental emissions. The present study carries out holistic review of the cement production process with a view to identifying the principal air pollutants, sources and associated environmental issues. The study also reviews the pollution control measures currently in use and calls for a concerted effort from researchers, industry operators and regulators at working to reduce emissions with a view to upholding environmental sustainability.

The acceptance of liquefied petroleum gas (LPG) cookstove has increased across the country in recent years; however, their performance has not been investigated and established. To achieve this, laboratory tests were carried out to evaluate the thermal efficiency, and industrial combustion analyser (E-instrument E8500) was then used to characterize and quantify the air emissions from combustion of conventional LPG cookstoves in the country. The average thermal efficiency for all tested burners was 66.267 ± 7.218% meeting Tier 4 of the International Organization for Standardization, International Workshop Agreement 11. The mean concentration of CO, NO_x, HC, and SO₂ was in the range of 3–530, 48–810.5, 99–4176, and 0–4,respectively,and the range of CO₂ was 1,792–3,592 mg/m³,which were compared with stationary source limit by Federal Ministry of Environment Standard, Nigeria. The toxicity potential of NO_x and SO₂ was below unity, 25% of the burners tested were below unity for CO, and HC was higher than unity for all tested burners. Most cookstoves met the guidelines for CO, NOx, and SO₂. Hence, LPG in Nigeria could serve as a source of energy for cooking.

Nigeria is a country blessed with vast oil and natural gas resources and due to inadequate management of resources most of the natural gas is flared. One of the most pressing challenges today is global warming. Gas flaring has been known to deliver carbon dioxide and other ozone depleting...

Oil spills contaminate water bodies and hence, cause the death of marine animals. The Niger Delta Oil contaminated water was treated by adsorption using sisal fibre activated carbon (SFAC) doped with silica nanoparticles (SNP) synthesized from Ofada rice husk which was carbonized at temperatures...
