“…An interesting trend was found for manganese and zinc, with these nutrients having lower available concentration in the soil and higher concentration in the root after FB7 treatment. Zinc and manganese are common nutrients in rice and their absorption can be enhanced by the application of calcium-containing fertilizers ( Luo et al, 2020 ). The other mechanism might be attributed to the competition effect between zinc and cadmium.…”

Due to the biomagnifying effect in the food chains, heavy metals will cause serious harm to the food produced in paddy soil, and then threaten human health. The remediation of soil heavy metals by the addition of amendments is a common method. However, the combination of the two amendments has been less studied and its effect is unknown. In this study, we investigated the effects of different concentrations of a lime and calcium-magnesium phosphate (CMP) amendments metal availability and paddy soil bacteria biodiversity. The experiment proves that the addition of 0.5 and 1.0‰ amendment can effectively reduce cadmium (Cd) availability and the cadmium content in rice to be below 0.2 mg/kg, meeting the national food safety level. The results demonstrate that increasing pH and phosphorous (P) in soil were two important factors decreasing available cadmium. Furthermore, biodiversity analysis of the treated soil showed that the amendment increased biodiversity. Proteobacteria and Chloroflex were the most abundant bacteria at the phylum level, followed by Acidobacterium and Nitrospirae. The abundance of Bacterodietes-vadinHA17, Syntrophaceae, and Thiobacillus increased as phosphorous increased. Cadmium passivation might induce those species.

“…Increased phosphorus treatment significantly decreased Cd accumulation in plants, as observed in wheat, spinach, and rice [ 18 , 19 , 20 ]. Previous phosphorus–cadmium experiments showed that cadmium toxicity impairs rice growth, but increasing phosphorus can repair the damage [ 21 , 22 ]. Cd-N responded similarly to phosphorus and cadmium treatments as other research, with Cd toxicity suppressing dry weight, plant height, and root length, but a moderate increase in phosphorus treatment could offset Cd toxicity, whereas Cd-T is a rice variety with high Cd accumulation, and Cd treatment had no significant effect on Cd-T growth ( Figure 1 and Figure S2 ).…”

Phosphorus treatment can reduce Cd accumulation and Cd toxicity in rice, but alterations in the internal regulatory network of rice during this process have rarely been reported. We have removed the effect of cadmium phosphate precipitation from the hydroponic system, treated a pair of different Cd-response rice varieties with different levels of phosphorus and cadmium and examined the changes in physiological indicators and regulatory networks. The results demonstrated that phosphorus treatment significantly reduced Cd accumulation in both types of rice, although the antioxidant systems within the two types of rice produced opposite responses. Overall, 3 mM phosphorus treatment to Cd-N decreased the expression of OsIAA17 and OsACO1 by 32% and 37%, respectively, while increasing the expression of OsNR2 by 83%; these three genes regulate the synthesis of auxin, ethylene, and nitric oxide in rice. IAA and NO levels in rice shoots increased by 24% and 96%, respectively, and these changes contribute to Cd detoxification. The cadmium transporter genes OsHMA2, OsIRT1, and OsABCC1 were significantly down-regulated in Cd-N roots after triple phosphorus treatment. These data suggest that phosphorus treatment can reduce Cd accumulation and enhance Cd resistance in rice by affecting the expression of signaling molecules.

Rumput laut (Caulerpa racemosa) merupakan salah satu makroalga yang memiliki kemampuan untuk mengakumulasi logam berat, sehingga dijadikan sebagai bioindikator pencemaran lingkungan. Wilayah pesisir Lamongan, termasuk di Kecamatan Brondong terdapat berbagai kegiatan industri. Buangan limbah kegiatan industri tersebut akan meningkatkan resiko pencemaran logam berat. Metode penelitian yang digunakan adalah observasi dengan analisis Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Analisis data yang digunakan yaitu kuantitatif dengan perhitungan berdasarkan Geo-Accumulation Index (Igeo), Contamination Factor (CF), dan Bio Concentration Factor (BCF). Hasil penelitian menunjukkan bahwa rumput laut (C. racemosa), air, dan sedimen dari tambak tradisional di Brondong, Lamongan mengandung logam berat (Pb, Cd, dan As) dengan konsentrasi yang rendah. Rata-rata konsentrasi Pb, Cd, dan As pada rumput laut (C. racemosa) berturut-turut adalah 0,0901 mg/kg, 0,0124 mg/kg, dan 0,2357 mg/kg. Konsentrasi Pb dan Cd pada air tidak terdeteksi, sedangkan rata-rata konsentrasi As pada air adalah 0,0158 mg/l. Konsentrasi Pb, Cd, dan As pada sedimen berturut-turut adalah 12,3 mg/kg, 0,171 mg/kg, dan 3,74 mg/kg. Nilai Igeo dan CF menunjukkan bahwa logam berat (Pb, Cd, dan As) mengindikasikan tingkat pencemaran dan tingkat kontaminasi yang rendah (0<Igeo<1 dan CF<1). Nilai BCF yang rendah juga menunjukkan bahwa tingkat akumulatif rumput laut (C. racemosa) dikategorikan rendah (BCF<100). Berdasarkan hasil penelitian ini, dapat diketahui bahwa tambak tradisional di Brondong, Lamongan tergolong aman untuk dilakukan kegiatan budidaya rumput laut (C. racemosa).
