Mn stimulated the development price and biomass production of Chlorella, which showed the highest carbon levels simply in the first few days. In both treatments, the nitrogen and protein contents remarkably increased. The photosynthetic pigments increased until the 14th day, with an increased level in the Zn-enriched option. An ever-increasing photochemical efficiency was seen after 1 week of treatment, once the microalgae grown in Zn- and Mn-enriched solutions revealed a slightly greater optimum photochemical efficiency than control. The autotrophic and managed growth system followed had been made to monitor the powerful stability of Zn and Mn items within the solutions and in the algal biomass. This technique has actually became beneficial in determining the optimal nutritional circumstances associated with microalgae, combined with the ideal temporal habits of both metal biosorption convenience of water remediation and factor bioaccumulation in the algal biomass.Immense epidemiological research reports have already been suggested about undesireable effects regarding the welding fumes from the health of the welders, particularly respiratory problems along with other physiological problems. Different types of welding components produce aerosols/fumes containing various metals including chromium (Cr) and manganese (Mn). In the present research, the welders of two age groups (adolescents and adults) were chosen; simultaneously the age-matched teenagers and grownups fit in with nonindustrial area as referents/control subjects. Biological samples (scalp hair) were collected from welders and referents, along with examined for Cr and Mn by electrothermal atomic consumption spectrometer, just before a
