Correlation Between Surface Water Quality Plankton Composition in Water Bodies in Hau Giang Province, Vietnam

Abstract

Hau Giang province, 2021). Notably, by the end of 2022, the province's economic growth reached 14.03%, ranking first in the Mekong River Delta and fourth in the whole country (Economic and Budgetary Department of Hau Giang province, 2022). Faced with the current situation of socioeconomic development, the pressure on the environment, especially the pressure on the surface water environment, is very great. With a system of interlaced rivers and canals such as Xang Xa No canal, Cai Con canal, Bung Tau canal, Cai Lon river, Ba Voi river, etc. important traffic to go everywhere in the province and other provinces in the region. With the main task of providing water for daily life, however, surface water in Hau Giang province has shown signs of pollution.

Recommending Surface Water Quality Monitoring for the Nature Reserve Using Multivariate Statistical Methods

“…In addition, there is no statistically significant difference in pH between the functional zones (p>0.05). It is consistent with previous studies on pH variation in Hau Giang province [6,8,9]. pH of surface water is generally varied from 6.64 to 7.34 [6,8,9].…”

“…It is consistent with previous studies on pH variation in Hau Giang province [6,8,9]. pH of surface water is generally varied from 6.64 to 7.34 [6,8,9]. This pH range can ensure the metabolism and biochemical reactions in the water environment take place normally and do not harm living organisms in water [20].…”

“…According to Giao (2020), DO levels in Hau Giang province varied from 3.2 to 5.2 mg/L of in-field canals and 4.6 to 4.7 mg/L in Hau River [6]. Another study in Hau Giang province also showed that DO level was in the range of 2.48 to 4.68 mg/L [9]. The average DO levels in Can Tho city and Soc Trang province were 5.68±0.16 and 3.11±0.64 mg/L, respectively [8].…”

“…The average TSS concentrations in the administrative and service zone (20±12.02 mg/L) and the main canal (29.22±18.9 mg/L) exceeded the QCVN 08-MT:2015/BTNMT column A1 (20 mg/L) [16]. Previous studies revealed that TSS in surface water in Hau Giang province varied from 23.6 to 101.8 mg/L [6,9], which is associated with navigation and domestic activities along the rivers. Moreover, TSS in the nature reverse is generally lower than in other regions, such as Can Tho (48.70±6.67 mg/L) and Soc Trang (95.79±8.45 mg/L) [8].…”

“…Moreover, surface water in this province also has problems with high concentrations of organic matter, nutrients, coliform, and iron [6][7][8]. According to Quang & Giao (2023), the enrichment of organic matter and nutrients in surface water in Hau Giang province was determined by the composition of the phytoplankton species [9]. This has resulted in the risk of high contaminant concentrations in the canals of the natural reserve.…”
