Sesarma boulangeri (Calman 1920), a type of freshwater invertebrate, was collected between January and December 2022 from three stations at the Shatt AL-Arab River, Basrah/ Iraq in order to conduct the research. The goal of the study was to determine the effect of organic pollution on autotomy in this species of crab. The organisms were subjected to varying levels of organic contamination in the river that came from sewage, farming activities, boat traffic, and transportation of products and oil derivatives using the organic pollution index (OPI). The left fifth leg's object was the reason for the autotomy. According to the characteristics of the water quality impacted by the oscillation, the cut creatures have varied indicators in response to the aquatic species. As a result, an extended period of growth for the regenerated portions is caused by the rise in organic contaminants in the water. Thus, the present findings indicate that S. boulengeri exposed to high amounts of organic pollution has a slower rate of replacing the cut component than control animals, that the growing bud is more vulnerable to distortion, and that the period of compensating for the cut part is longer. According to the OPI result shows that the first station has significant difference (P<0.05) as compared to the sconed and third stations wish did not difference.

The current study has evaluated Shatt Al-Arab water using organic pollution index. The study included three stations, the first Al-Sharash, the second Al-Salhiya and the third area Al-Dweab. Water samples were monthly collected from December 2017 to November 2018. Five environmental parameters were used to calculate the organic pollution index (OPI) including Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Active nitrate (NO3), Ammonium ion (NH4) and Total Phosphate (TP). The highest biological oxygen demand was 9 mg.l-1 at Al-Sharash station in July and the lowest values 1mg.l-1 in the Al- Dweab station during December, January, February and April. The highest chemical oxygen demand (250 mg.l-1 was recorded at Al-Sharash station in September and the lowest value was 6.2 mg.l-1 in Al-Dweab station during December. Nitrates was recorded the highest value 41.51 mg nitrogen-nitrate.l-1 at Al-Salhiya station in May and lowest value 1.49 mg nitrogen- nitrate.l-1 at Al-Sharash station during December. The ammonium ion was recorded in highest value 7.7 mg.l-1 at Al- Salhiya station in December and the lowest value 0.5 mg. l-1 at Al-Sharash station during June, while phosphate value was 0.23 and 1.99 mg.l-1 were recorded at Al-Sharash station in August and July respectively. The highest value of organic pollution index was 2.56 at Al-Salihiya station in August and lowest value 0.69 in the Al-Dweab station in April, while the annual rate of organic pollution index for the first, second and third stations were 1.55, 1.81 and 1.47 respectively, and 1.61 for Shatt Al-Arab water.
