In this paper, we present the multivariate distribution of independent Lévy flight jump diffusion molecules that cause water pollution. We consider that the waiting time of this jump has a Gaussian distribution. Rather than studying the statistical properties of this distribution in water, we estimate the length of the jump distance parameters for each molecule. These estimated jump distances of the molecules are used to predict the proportion of pollution in a large area of the sea.

We consider linear flows of a Lévy flight jump particle that moves randomly in the fluid reactive anomalous transport with random waiting time depending on the Gaussian distribution. The particle aims to meet another Brownian particle in this fluid. From the viewpoint of a probability theory, we present a theoretical and analytical study that gives conditions which make the expected value of the first meeting time between the two particles finite.
