Assessment of Pb, Cd, Cr and Ni in Water and Water Hyacinth (Eichhornia crassipes) Plant from Woji Creek, Rivers State, Nigeria

Abstract

This study evaluates the levels of Pb, Cd, Cr and Ni and the potential ability of water hyacinth (Eichhornia crassipes) plant to bioaccumulate these metals in Woji Creek, Rivers State, Nigeria by collecting water and water hyacinth samples along a 1.3 km stretch of the creek between 2018 and 2019 for analysis. Water samples and plants were collected from five stations across the creek from June to October of both years. The trend of metal concentration in the surface water is Pb > Cr > Ni > Cd in 2018 and Pb > Ni > Cr > Cd in 2019. In 2018, metal concentration in the root are in the order: Cr > Ni > Pb > Cd, while the trend for the shoot is Cr > Pb > Ni > Cd. In 2019, Cd was detected in the roots ranging from 1.009 ± 0.001 to 9.545 ± 0.006, while Pb ranged from 0.298 ± 0.006 mg/kg to 121.006 ± 0.005 mg/kg. There was substantial bioaccumulation of Pb, Ni and Cr in the roots with most plant roots having BCF > 1. In the shoot, BCF was > 1 for Pb and Cr only, while Ni had BCF < 1. The findings from this research also assert that the E. crassipes can be used in the application of rhizofiltration as phytoremediation technique in Woji creek.

Ecological and human health risk assessment of total petroleum hydrocarbons in surface water and sediment from Woji Creek in the Niger Delta Estuary of Rivers State, Nigeria

“…The creek serves as a route of transportation into the city by water transport through the Bright of Bonny into the City of Port Harcourt. For this reason, boats and barges are manufactured and maintained at several points along the creek, therefore creating a potential for pollution due to these anthropogenic activities ( Dibofori- Orji et al., 2019 ; Ibezim-Ezeani and Ihunwo, 2020 ). Fishing is also a major use of the creek by local communities.…”

Kinetics and prediction modeling of heavy metal phytoremediation from glass industry effluent by water hyacinth (Eichhornia crassipes)

“…Water hyacinth (a member of the family Pontederiaceae) is a hyperaccumulator plant species having a distinct capacity to absorb various heavy metals from the contaminated sites (Ibezim-Ezeani et al 2020). It grows in the local water bodies, lakes, rivers, dominated by high nitrogen, phosphorus, mineral, and heavy metals.…”

Phytoremediation of Nickel via Water Hyacinth for Biocarbon‐Derived Supercapacitor Applications

“…[ 6–9 ] Many of these contaminants play a vital role in biological processes such as the enzymatic activity glyoxalase‐I and urease for nitrogen metabolism; however, large quantities cause damage to DNA, creating mutagenic effects in both plants and animals. [ 10,11 ] Nickel in particular is the second most absorbed metal in plant roots and third in shoots, indicating readily available uptake capabilities of plants. [ 10 ] Here, amino acids such as histidine regulate Ni 2+ uptake and act as chelators in the form of complexes.…”

“…Initial uptake of Ni–H 2 O complexes by root systems gives way to Ni‐amino acid multiplexes during natural biological processes. [ 10 ] WH's viability as a hyperaccumulator comes from its ability to upregulate and downregulate specific proteins to manage toxins. [ 12 ] WH also contains shock proteins that have certain antioxidative properties, allowing them to handle free radicals species generated from metal ions.…”
