“…The regression coefficients (R 2 ) of the calibration were greater than 0.99, indicating that there was a very good association between absorbance and the concentration of metals. The detection limits were calculated as the concentrations that provide signals equal to three times the standard deviations of the blanks [ 26 ]. The limit of quantification (LOQ) is the lowest concentration of an analyte in a sample and quantitatively calculated with acceptable uncertainty using 10 times the standard deviation of the blank.…”

“…If the value of HI ≤ 1, it is assumed that non-carcinogenic risks have no substantial impact. If HI > 1, however, there is a risk that non-carcinogenic effects will occur, and the likelihood increases as HI increases [ 26 , 36 ].…”

Heavy metals can now be considered as natural constituents of the environment, but indiscriminate use for human purposes has altered their geochemical cycles and biochemical balance. This study was conducted in Kano metropolis to assess the heavy metals contamination in soils and crops where wastewater is used for irrigation. Soil and crop (Cucumber, Maize, Onion and Spinach) samples were randomly collected from 3 sites, digested and analyzed for Cd, Cr, Ni and Pb using Atomic Absorption Spectrophotometer (AAS). The results were compared with the standard guidelines set by World Health Organization (WHO) and were used to estimate the health risks of these heavy metals via consumption of the crops. The concentrations of heavy metals found in the soil (4.76 – 52.38 mg/kg, 2.45 – 3.43 mg/kg and 7.65 – 14. 21 mg/kg for Cr, Ni and Pb respectively) were within the acceptable threshold of 100, 50 and 100 (mg/kg) for Cr, Ni and Pb respectively. Cd was recorded in the range of 3.67 to 4.28mg/kg, which is above the acceptable limit of 3.00mg/kg in all the soil samples. The pH values were below the normal range while the Electrical Conductivity (EC) were all above the normal range. For the plant samples, the mean concentrations of the heavy metals studied were above the maximum acceptable threshold recommended by WHO/FAO except Ni. The Estimated Daily Intake (EDI) concentrations of Cd and Cr in all plant samples were above the acceptable tolerable daily intake (PTDI) limit as recommended by European Food and Safety Agency (EFSA). Hazard Quotient (HQ) value of Cd and Pb and the Hazard Index (HI) values for all the samples were greater than 1, which indicates that there is high potential of health risk associated with the consumption of the contaminated crops. The study highlights that irrigation with untreated wastewater is, likely, the major source of heavy metals contamination to the soils and plants examined. It is, therefore, recommended that use of wastewater for irrigation farming should be discouraged.

Review of natural compounds for potential psoriasis treatment

Psoriasis represents an immune-mediated disease with an unclear cause that’s marked by inflammation triggered by dysfunction in the immune system, which results in inflammation in various parts of the skin. There could be obvious symptoms, such as elevated plaques; these plaques may appear differently depending on the type of skin. This disease can cause inflammation in the elbows, lower back, scalp, knees, or other regions of the body. It can begin at any age, although it most commonly affects individuals between the ages of 50 and 60. Specific cells (such as T cells) have been observed to play an obvious role in the pathogenesis of psoriasis, in addition to specific immunological molecules such as TNF-, IL-12, IL-23, IL-17, and other molecules that can aid in the pathogenesis of psoriasis. So, during the past two decades, biologists have created chemical drugs that target these cells or molecules and therefore prevent the disease from occurring. Alefacept, efalizumab, Adalimumab, Ustekinumab, and Secukinumab are a few examples of chemical drugs. It was discovered that these chemical drugs have long-term side effects that can cause defects in the patient's body, such as the development of the rare but life-threatening disorder progressive multifocal leukoencephalopathy (PCL). Its rapidly progressive infection of the central nervous system caused by the JC virus and other drugs may cause increased production of neutralising anti-drug antibodies (ADA) and the risk of infusion reactions like pruritus, flushing, hypertension, headache, and rash. So, our context intends to talk in our review about natural products or plants that may have therapeutic characteristics for this disease and may have few or no side effects on the patient's body.
