“…This kind of emulsion may easily transfer with the seawater or groundwater into the coastal aquifer, causing a much larger scale of oil contamination in the aquifer compared with the condition when no emulsion forms. Nevertheless, few studies have been conducted to understand the stability of this kind of emulsion and the transfer and transformation processes of the spilled oil into the coastal aquifer in the presence of surfactants [9][10][11][12].…”

After oil spills in the coastal aquatic environment, the physical and chemical properties of the spilled oil may change under the influence of the chemical dispersant and form emulsions in the water. This paper presents the results of a laboratory study on the influence of chemical dispersant to the properties of crude oil. The experiments were conducted using two widely-used surfactant GM-2 and BH-X, two crude oil samples and artificial seawater. Density, viscosity and emulsification rate of crude oil with different amounts of dispersant added was measured. The results show that viscosity of the crude oil was highly influenced by the chemical dispersant. The maximum emulsification rate of the Saudi Arabian middle crude oil was 54.1% and 57.4% with the dispersant to oil ratio above 0.8, whereas the emulsification rate of the heavy oil was significantly lower than the middle oil with both of the two types of chemical dispersant.

The context, which allowed to write this article is the fact that we have noticed an increase in the environmental impact caused by the poor management of car parks and fuel sellers as well as the proliferation of service stations that do not respect any standards. The illegal storage and marketing of petroleum products, especially gasoline, in the city of N'Djamena is the main factor of vulnerability and criticality of air pollutants, thus demonstrating the growing environmental impact in the city of N'Djamena. The presence of Polycyclic Aromatic Hydrocarbons (PAHs) as well as that of fine particles which are part of the Persistent Organic Pollutants (POPs) and characterize by their toxicities, their persistence in the environment, their bioaccumulation in living tissues, and their long-distance transport. Thus, the main objective of this work is to determine and evaluate the physical properties of gasoline and the presence of fine particles in the ten districts of the city of N'Djamena. These are the species sold on the street and presenting a danger to users. The main idea would be to look for gas stations and points of sale that comply with the regulations in force and those that do not. Then physical analyses were carried out on different types of gasoline consumed and then the air quality was measured with a Purple Air sensor. In conclusion, a complete structure of the ten districts with their degrees of pollution as well as the number of gas stations and fuel sellers on the street will be listed.
