“…This indicates that the study area was generally contaminated with petroleum hydrocarbon and the continuous consumption of seafood from the area may pose a public health hazard. However, the THC levels in the study area, was similar to that in other studies in the Niger Delta by [11]: surface water -42.05mg/l and sediment -184.89µg/g; [20] surface water -149mg/l, sediment -339.2µg/g and biota -196.9µg/g and [23] sediment -528.25µg/g.…”

Ibigoni Clinton et al.: Evaluation of total hydrocarbon levels in some aquatic media in an oil polluted mangrove wetland - ), indicating a polluted environment. THC levels in water at the wellhead stations were above 10mg/l being the maximum recommended limit by the Federal Ministry of Environment (FMENV) Nigeria. There was a pronounced seasonal variability with the highest being in the dry season (P < 0.05) due to the higher level of increased oil activity in that season. THC levels in water correlated significantly (r = 0.927) with THC levels in the sediment (P < 0.01). The implication is that as the THC remains within the surface water column in relation to the sediment the more the organisms in the environment are impacted. This is shown by the significant correlations (P<0.01) of THC between the organisms and their surrounding media. The high levels of THC in the surface water and sediments of these stations suggest that aquatic life water quality may adversely influence biological functions of exposed species, while the level in the Tympanotonus fuscatus and the Periophthalmus papillio calls for concern as it can have some health-risk implications in man who is the final consumer.

“…In another research on performance of coconut shell ash (CSA) and palm kernel shell (PKSA) ash as partial replacement for cement in concrete by Oyedepo et al (2015); the research demonstrate that the utilization of CSA and PKSA as a partial replacement for cement in concrete, at lower volume of replacement, will enhance the reduction of cement usage in concretes, accordingly decreasing the production cost and the ecological contamination brought on by the dumping of the agricultural waste. Osarenmwinda and Awaro (2009) Periwinkle (Tympanotonusfuscatu sand Pachymelaniaaurita) is a common name for a group of molluscan shellfish with either smooth or rough spiral shells (Ideriah, et al, (2006). There are hundred species each of two genera of Nigerian Periwinklesradula (a brackish water habitat) and Pachymelaniaaurita(a fresh water species) (Bukola et al, 2006;Uwadiae, et al 2009).…”

ABSTRACT:The properties of lightweight concrete, such as aggregate impact value, aggregate crushing value and compressive strength were assessed utilizing periwinkle shell (PWS) as partial replacement for coarse aggregate. Standard mix of 1:2:4 with varying percentages of 0%, 10%, 20%, 30%, 40%, 50% and 100% partial replacement of PWS using water/cement (W/C) ratio of 0.55 was used. Seventy two cubes of 150 mm x 150 mm x 150 mm were casted; allowed to set for 24 hours before remolding, and were properly cured. The strength characteristics of each cube were evaluated using Compressive Testing machine at the curing ages of 7, 14, 21 and 28 days. The ACV and AIV obtained are 31.59% and 22.61% respectively which is within the acceptable limit. An optimum compressive strength value of 16.79 N/mm 2 and 16.71 N/mm 2 was obtained with the addition 20% and 30% partial replacement of coarse aggregate with PWS in 28 days. These values are within 15-25 N/mm 2 and it is suitable for Lightweight concrete. The research demonstrates that the utilization of PWS in structural/insulating lightweight concrete, at lower volume of replacement, will reduce the utilization of granite in concrete. Thus, decreasing the production cost of concrete and the ecological contamination brought about by the dumping of periwinkle shell. © JASEM http://dx.doi.org/10.4314/jasem.v20i3.2

“…Periwinkles are shellfish found in the littoral region of the sea, brackish or estuarine water which are seasonal submerge regions like the mangrove swamps [9]. They crawl about under water but usually remain passive when left uncovered by the tide [10]. The two species of periwinkles commonly found in Niger Delta coastal region of Nigeria are Tympanotonus fuscatus and Pachymelania aurita [11].…”

For the present study, edible parts (meat) from freshly harvested Tympanotonus fuscatus, Pachymelania aurita and Thais coronata were processed into powders and analyzed for proximate composition, amino acid profile and mineral content. The mean values obtained were compared with each other. Results showed that all the parameters determined varied among the three gastropod species. Powders prepared from the three species had high protein and low fat contents. The protein content ranged from 41.51% for T. fuscatus meat powder to 58.45% for T. coronata meat powder. The fat, ash, crude fibre and carbohydrate contents ranged from 2.94-3.19%, 10.26-13.85%, 0.38-0.46% and 25.13-36.17% respectively. The caloric value ranged from 358.71-371.82kcal/100g. The total amino acid ranged from 77.76g/100g protein for T. fuscatus meat powder to 83.53g/100g protein for T. coronata meat powder while the total essential amino acid ranged from 32.97g/100g protein for T. fuscatus meat powder to 37.77g/100g protein for T. coronata meat powder. Majority of essential amino acid chemical scores were above 100% except for lysine that ranged from 80.00% to 97.24%, tryptophan was 88.18% for T. fuscatus and 90.00% for P. aurita while threonine was 95.26% for T. coronata and 99.41% for T. fuscatus powder. The Ca, K, Na, Mg, Fe and Zn ranged from 41. 38-79.02mg/100g, 29.51-42.10mg/100g, 68.24-81.16mg/100g, 140.00-208.05mg/100g, 9.05-11.62mg/100g and 2.64-3.08mg/100g respectively. The high protein and low level of the crude fibre contents in the meat powders will make them suitable for use in complementary foods. Also, the low fat content in the meat powders suggests that they could be incorporated in foods for hypertensive individuals and those that have fat related diseases. Successful application of these powders in food product formulation and product development will lead to increase utilization of these nutritious, cheap and readily available sources of meat protein.
