A few days ago, 61 academicians called for the industrialization of genetically modified rice, raising concerns about the safety of GM foods. According to a report from the Ministry of Agriculture, they plan to increase public education on genetic modification, foster a supportive public opinion environment for biotech applications in China, and speed up the revision of laws related to GMOs. On the 21st, Professor Huang Kunlun from the College of Food Science and Nutritional Engineering at China Agricultural University announced that the pig feeding test for BT gene-resistant rice had been completed. The results showed that transgenic BT rice is nutritionally and safely equivalent to non-transgenic rice.
Pigs have digestive systems very similar to humans, making them ideal subjects for testing the safety of genetically modified crops. According to media reports, the Ministry of Agriculture commissioned a 90-day feeding trial of genetically modified rice on miniature pigs at China Agricultural University. Professor Huang Kunlun, a leading expert on GM rice, explained via email that the experiment aimed to evaluate the effects of BT rice on pigs. He emphasized that pigs are an excellent model for studying human digestion due to their similar gastrointestinal tract and omnivorous diet.
The pigs involved in the study showed no signs of poisoning or death during the 90-day period. They had smooth fur, normal movement, healthy appetites, and good growth. However, despite these findings, public skepticism remains high. Many people question whether such short-term tests can truly reflect long-term health impacts. Critics argue that 90 days is only a fraction of a pig’s lifespan, which would be equivalent to just a few months in a human's life. This raises doubts about whether such studies can effectively assess potential toxicity over time.
Currently, China has approved safety certificates for genetically modified crops like cotton, rice, corn, and papaya, but commercial planting is still pending. Under the Seed Law, GM crops require additional certifications before they can be commercially cultivated. So far, only cotton and papaya are officially planted, while GM rice and corn remain unapproved.
Additionally, several imported crops, including soybeans, corn, rapeseed, and sugar beet, are genetically modified and must pass China’s safety standards before being used in processing. Despite this, many consumers remain skeptical about the safety of GM foods.
Recent online surveys show that 89% of participants believe GM foods are unsafe, and 94% oppose their commercialization in China. This reflects a growing public concern that is not purely scientific, but rather rooted in a lack of trust in institutions and transparency.
In 2004, the U.S. National Academy of Sciences warned that GM crops could pose risks to both human health and the environment. In 2009, the American Academy of Environmental Medicine reported potential health risks, including infertility, immune issues, and organ damage in animals fed GM foods. These findings led to calls for doctors to advise patients against consuming genetically modified products.
Some experts, including 61 Chinese academicians, have pushed for faster industrialization of GM rice, arguing that delays hinder scientific progress. However, critics suggest their motivations may be more aligned with research funding and economic interests than public health.
According to ISAAA data, the top five countries growing GM crops are the U.S., Brazil, Argentina, Canada, and India. None of these countries have yet commercialized GM rice or wheat. As the debate continues, the long-term impact of GM foods on public health and the environment remains a critical concern for many.
Industrial Online PH Electrode
Description
Industrial pH probe, also called industrial PH Sensor, is key core sensing components for measuring the pH value of industrial water. This specific type of Industrial pH electrode typically lacks direct signal output and necessitates conversion into an electrical signal via a transmitter. It represents an online composite industrial pH electrode, a harmonious blend of a glass indicator electrode and a reference electrode. The fundamental principle of pH measurement involves utilizing a working cell, composed of a measuring electrode and a reference electrode, to quantify the potential difference within the solution. This process leverages the linear relationship between the pH value of the solution under test and the potential of the working cell, thereby enabling online pH monitoring.
Industrial pH, measured by an industrial pH probe, indicates the acidity or alkalinity of industrial aqueous solutions. It reflects the ratio of total hydrogen ions to total substances in the solution. As a quantitative measurement of the acidity or alkalinity of aqueous solutions, it is an important chemical indicator of great significance for industrial production, equipment protection, and environmental protection. Strict control of solution pH during industrial production, achieved through an industrial pH probe, is essential to meet the requirements of product quality, equipment life, and environmental protection.
Â
The importance of an industrial pH probe & sensor in assessing industrial pH cannot be overstated:
Impact on product quality: In numerous industrial production processes, including electroplating, the chemical industry, and the pharmaceutical industry, the pH value of the solution plays a crucial role in determining product quality and performance. Thus, the deployment of an industrial pH probe to tightly control the solution's pH in these processes is indispensable.
Impact on equipment life: When the pH of industrial wastewater veers too high or too low, it can lead to corrosion or damage to water treatment equipment components such as pipes, pumps, and gate valves, thereby compromising equipment lifespan and performance. An industrial pH probe plays a vital role in preventing such occurrences.
Environmental protection: The pH range conducive to biological survival is narrow, prompting most countries to strictly regulate effluent pH values between 6 and 9. When industrial wastewater pH falls outside these standards, aquatic organisms and the ecological environment may suffer. An industrial pH probe is crucial for ensuring compliance with these environmental regulations.
Â
Application
An industrial pH probe and an industrial pH sensor are widely used and are commonly employed in water quality monitoring based on pH in industries such as sewage treatment, chemicals, petrochemicals, textiles, and electroplating.
