Web2 sep. 2024 · Increased concentrations of heavy metals in soil due to anthropogenic activities pose a considerable threat to human health and require constant attention. This study investigates the spatial distribution of heavy metals (Cd, Pb, Zn, Sb) and metalloids (As) in a typical alluvial–lacustrine transition basin and calculates the bioavailable forms … WebBy the symmetry of the normal distribution, we can integrate over just the positive portion of the integral, and then multiply by two: G ( v) = 2 ∫ 0 v 1 2 π exp ( − z 2 2) d z Okay, now let's do the following change of variables: Let z = y = y 1 / 2 So, d z = 1 2 y − 1 / 2 d y = 1 z y d y z 2 = y, z = 0 ⇒ y = 0 z = v ⇒ y = v Doing so, we get:
