What percentage of the PCPs examined contained UV filters?

From last test in Math I didnt read the instruction properly I think its mean to search a data from google or search engine so I think I mess up but in this part I see the research that you want me to read so I apologize for miss understand in the first test that I has done. Let start The study reports that UV filters were found in 58% of the PCPs examined.

Firstly I see the document that you provide 5 document I decide that the time is not enough to read every document so I use skimimg method to looking for the answer. The answer is mention in Materials Today: Proceedings in Table 1 page 2 in the document.

Which of the following fragrances is considered a weak allergen but found frequently in PCPs?

Limonene is frequently found in PCPs and is a known weak allergen​.

In the same document in section 3.2 pages 2 "that the most frequently identified fragrances were limonene (73.3%)".

What does the term 'emerging pollutants' refer to in the context of the study?

The term refers to persistent and bioaccumulative chemicals that pose environmental and health risks.

" emerging evidence suggests that some accumulate in body tissues and negatively impact humans and animals, impacting the endocrine systems and the environment since they are continuously being released and may not degenerate easily the environment." This sentences is what I see in the abstract.

โจทย์ ปรนัย
What percentage of skin care products examined contained fragrances?

Approximately 70% of skincare products in the study contained fragrances​.

In the same document " approximately 70% of these products contained fragrances." they mentioned this key point.

According to the study, which substance is toxic to aquatic life and can affect fertility?

This fragrance is noted for its toxic effects on aquatic life and its potential to impact fertility​.

In the same document they mention "In addition, alpha-isomethyl ionone is toxic to aquatic life "

โจทย์ ปรนัย
Based on the study, which regulatory action is recommended due to the detection of harmful ingredients in PCPs despite their ban?

The study suggests stricter regulations on product labelling and testing to address the use of harmful ingredients.

"The lack of set rules and regulations around PCP labelling and inconsistency in chemical regulation promotes the distribution of harmful chemicals into the environment" This what they mentioned in pafe 2 of the same document.

โจทย์ ปรนัย
What are the potential health risks associated with chemicals in PCPs as mentioned in the study?

The chemicals in PCPs are linked to endocrine disruption and estrogenic activity, posing significant health risks.

In the introduction in the same document they mentioned this sentences "The reported health risks associated with chemical ingredients in PCPs (such as ultraviolet (UV) filters, parabens, and phthalates) include potential endocrine disruption and exhibition of estrogenic activity"

What is the primary purpose of Process Analytical Technology (PAT)?

PAT aims to enhance quality assurance by monitoring critical process parameters and attributes in real-time.

"Process Analytical Technology (PAT) is a systematic approach for monitoring of process parameters" This is the sentences which shows in Abstract of Advanced Powder Technology. After this question I think this questionare going to ask the question in by the individual document like question will not be shuffle the document.

โจทย์ ปรนัย
Which technology is often combined with reliable in-line sensors to enhance PAT systems?

MSMs are crucial for interpreting complex datasets and improving the efficiency of PAT systems.

"PAT systemsinclude a combination of reliable in-line sensors, spectroscopic instruments and Multivariate StatisticalMethods (MSMs)" this sentences included in Abstract of Advanced Powder Technology document now I sure that my hypothesis is correctly.

โจทย์ ปรนัย
What does data fusion primarily help improve in PAT systems?

Data fusion integrates datasets from multiple sources to enhance the robustness and accuracy of PAT systems​

"Data fusion is a data-driven approachby which complementary data displaying significant variations could be merged with the desire of increasing the model performance and robustness" This is the sentences that shows in 3.1.Datafusionapproaches.

โจทย์ ปรนัย
Which is NOT a listed advantage of continuous processing of powdered and granule products?

Continuous processing improves productivity, quality, and financial efficiency but does not compromise safety standards​

"...in one production system is getting more attention due to advantages inimproved productivity,.." As you can see there no mention about any Decreased safety standards this sentences mentioned in Introduction topic.

โจทย์ ปรนัย
Which of the following is considered a Critical Quality Attribute (CQA) for powdered and granule products?

Particle size is a key CQA that affects product performance and quality.

" key CQAs include homogeneity in powder mixtures [7], particle size." As you can see they clearly mentioned about the particle size.

โจทย์ ปรนัย
What does the integration of multiple unit operations in one production system characterize?

Integrating unit operations is a hallmark of continuous processing, enhancing efficiency and quality.

"Continuous processing of powdered and granule products comprising the integration of multiple unit operations" this sentences from Introduction topic shows clearly.
