Biochemical indicators of occupational health hazards in Nkalagu cement industry workers, Nigeria

Anicteric hepatoxicity: a potential health risk of occupational exposures in Nigerian petroleum oil refining and distribution industry

“…Contrary to the findings in the present study, elevated levels of AST and ALT were reported for those occupationally exposed to toxic substances, indicating susceptibility to Anicteric hepatitis [63,64]. The study of Dioka et al [65] revealed that while ALT and AST activities were elevated in occupationally exposed artisans than in controls, ALP activity was significantly lower in the exposed subjects than in controls.…”

“…Based on these submissions, it could be said that part of the health risks associated with occupational exposures in the Oil and Gas industry are among others, the possible development of bone diseases with increased osteoblastic activity, liver diseases with involvement of the biliary tracts, toxic hepatitis, liver cirrhosis, malignancies of various body sites including bronchial carcinoma, hepatoma and leukaemia, etc. In fact, apart from the various degrees of accidents and injuries previously reported among these same petroleum refining and distribution workers [63], results also indicated that some of the above highlighted conditions including liver diseases, made reckonable contributions to the morbidities and mortalities recorded in this industry [64], thus suggesting the presence of organs/systems toxic agents in this work environment. Serum alkaline phosphatase electrophoreses study is therefore highly warranted in a further study of these oil refining and distribution workers to establish the actual isoenzyme fraction of alkaline phosphatase responsible for the increasing pattern observed for this enzyme among this segment of workers, and thus establish on a firmer basis some or all of these possible health risks among the oil workers.…”

Effect of Cement Dust Exposure on Lung Function among Residents of Kalambaina Community in Sokoto State, Nigeria

“…Some researchers in Nigeria have studied the effect of chronic exposure to cement dust on the health of cement factory workers and have found cement dust deleterious to health. [6][7][8][9][10][11] Oguntoke and his colleagues in their study in Ewekoro Local Government Area, South-Western Nigeria on both cement factory workers and residents of Ewekoro found that the health profile of the factory workers and some residents of neighbouring communities showed high levels of respiratory and skin infections. 12 A study carried out on the workers of this cement factory in Kalambaina found that cement dust was deleterious to health of the workers.…”

Prevalence of Cement Dust Exposure Related Illnesses among Residents of A Mining Community in North West Nigeria

“…10 In a community in which such an industrial activity has been carried out on for 44years, its impact on the health of residents warrants attention and needs to be investigated. A few studies in Nigeria [11][12][13][14][15][16] have examined the effect of chronic exposure to cement dust on the health of cement factory workers. A study carried out on the workers of this cement factory found that the vital capacity and forced expiratory volume for one second percent were significantly lower in cement factory workers than in control subjects,(P<0.001 and P<0.005) respectively.…”
